If you’ve ever caught a rerun of Good Times on some random cable channel at 2:00 AM, you know exactly who Jimmie "JJ" Walker is. The lanky frame, the wide grin, and that iconic "Dy-no-mite!" catchphrase defined an entire era of 1970s television. But time moves fast. One minute you're the teenage heartthrob of the South Bronx, and the next, people are scouring the internet trying to figure out if you're still touring or just enjoying a quiet retirement.
So, let's get right to the number everyone is looking for.
As of early 2026, Jimmie Walker is 78 years old. He was born on June 25, 1947. This means he’ll be hitting the big 79 this coming summer. It’s wild to think about because, in the minds of millions, he’s still that 17-year-old kid living in the projects with Florida and James Evans. Honestly, seeing him today is a bit of a trip; he’s still got that spark, but the years have definitely added some gravitas to the man behind the "Kid Dyn-o-mite" persona.
How Old Is JJ Walker and Why Does Everyone Keep Asking?
The reason people are so fixated on his age usually boils down to nostalgia—and a bit of disbelief. Jimmie Walker didn't just play a character; he became a cultural phenomenon. When Good Times premiered in 1974, Walker was already in his mid-20s, playing a teenager. That’s a classic Hollywood move, right? By the time the show wrapped in 1979, he was 32, yet most of the audience still viewed him as a youngster.
Since then, Jimmie has stayed remarkably active. He didn't just disappear into the "where are they now" file. He’s been a staple on the stand-up comedy circuit for over five decades. If you’ve seen him perform recently—and he still does plenty of dates—you’ll notice he’s still got that high-energy delivery, though his material has shifted from teenage antics to the more cynical, sharp-tongued observations of a man who’s seen it all.
The South Bronx Beginnings
To understand Jimmie's longevity, you've gotta look at where he started. Born James Carter Walker Jr. in Brooklyn but raised in the South Bronx, his early life wasn't exactly a sitcom. We're talking about a guy who grew up in the projects during a period of massive urban decay.

He wasn't always the class clown, either. Believe it or not, Jimmie was actually a bit of a "mathlete" in school. He attended Theodore Roosevelt High School and later got into a program called SEEK (Search for Education, Evaluation, and Knowledge). It was there, while studying literature and speech, that he realized he could make people laugh. Not just "chuckle" laugh, but "fall out of their chairs" laugh.
By the late 60s, he was working as a delivery boy and a vendor at Yankee Stadium while trying to break into the New York comedy scene. He was 22 when he started doing stand-up professionally in 1969. That’s a long time to be on the road, folks.
The Good Times Era: More Than Just a Catchphrase
When people ask how old is JJ Walker, they are usually reminiscing about the 1974–1979 run. That five-year stretch changed everything. Jimmie was the first breakout Black teen star on a sitcom, but it wasn't all sunshine and rainbows behind the scenes.
There’s been plenty of talk over the years about the tension on the set. If you read his 2012 autobiography, Dyn-o-mite!, or catch any of his recent interviews (he's been quite vocal lately, even at 78), he doesn't sugarcoat it. His co-stars, Esther Rolle and John Amos, weren't exactly thrilled that the show’s focus shifted from serious social issues to JJ’s "buffoonery."
- The Conflict: Rolle and Amos wanted a more serious depiction of Black family life.
- The Reality: The audience wanted the "Dy-no-mite!" kid.
- The Result: Amos was eventually let go, and Jimmie became the face of the franchise.
It’s interesting to look back at that through a 2026 lens. Jimmie was a young man in his late 20s caught between being a professional actor and a massive corporate "product." He’s admitted in recent years that he didn't really have a close relationship with his castmates outside of work. It was a job. A very high-paying, fame-inducing job, but a job nonetheless.
Jimmie Walker in the 2020s: Still "Dy-no-mite"?
It’s easy to assume that someone who was famous fifty years ago has just hung up the mic. But Jimmie is a bit of a workaholic. Even at 78, he’s still out there. You might have seen him in those Medicare commercials that seem to run on a loop—honestly, those ads are probably why half the people are Googling his age right now.

He’s also made headlines for his politics, which are... let's just say, "unexpected" for a guy who came up in the 70s. He’s been a frequent guest on conservative talk shows, often describing himself as a "logic-ist" rather than sticking to a specific party line. It’s stirred up some controversy, but Jimmie has always been the kind of guy who says exactly what’s on his mind, whether people like it or not.
Career Milestones by the Decades
- 1960s: Started stand-up and worked as a radio DJ at WRVR.
- 1970s: The Good Times explosion. Time Magazine named him "Comedian of the Decade."
- 1980s-90s: Starred in short-lived shows like At Ease and Bustin' Loose, and did a ton of guest spots on everything from The Love Boat to Star Search.
- 2000s-Today: Heavy focus on touring and cameo roles in shows like Everybody Hates Chris.
Dealing With the "Legacy" Factor
One thing you've gotta respect about Jimmie is that he’s never tried to hide from JJ Evans. Some actors get bitter about their most famous role, but Jimmie leaned into it. He knows that "Dy-no-mite!" paid for his house and kept him in the public eye for half a century.
However, at 78, he’s also reflecting more on the "loneliness" of fame. He’s been very open about the fact that he never married and doesn't have children. In a recent interview, he mentioned that his life is mostly about the road and the stage. It's a bit of a bittersweet reality—the man who made millions of families laugh every Tuesday night at 8 PM goes home to a quiet house.
What You Should Know If You’re a Fan Today
If you’re looking to keep up with Jimmie in 2026, here’s the deal:
- Check the Tour Dates: He still performs at comedy clubs and theaters across the country. He’s often paired with other legends like Marsha Warfield or Lenny Clarke.
- The Medicare Ads: Yes, that's him. He’s become the face of those "Money Map" and insurance commercials. Love them or hate them, they've introduced him to a whole new generation.
- The Memoir: If you haven't read Dyn-o-mite!, grab a copy. It’s surprisingly blunt and offers a perspective on 70s TV that you won't get anywhere else.
It’s sort of incredible that we’re still talking about a character that debuted over 50 years ago. Whether he’s 78, 80, or 90, Jimmie Walker has secured his spot in the pantheon of TV legends. He’s a survivor of an industry that usually chews people up and spits them out within a decade.
Next time you see him on screen, don't just think about the catchphrase. Think about the guy from the South Bronx who figured out how to turn a lanky frame and a big mouth into a career that spanned six decades. That’s the real "dy-no-mite" story.
