"Dy-no-mite" was one of the most famous catch-phrases in TV history.
Now, more than 30 years after the classic 70s sitcom Good Times went off the air, Jimmie "J.J." Walker is back.
In his new memoir, Dy-no-mite, the comedian is spilling secrets from the Good Times set.
He tells INSIDE EDITION the cast members never socialized with each other.
"Nobody ever spoke, so there were no problems," said Walker.
Walker, now 65, became a break-out star on the show, thanks mainly to his catchphrase, "Dy-no-mite."
Some of the other actors, particularly the late Esther Rolle, reportedly resented all the attention Walker was getting, so executive producer Norman Lear restricted how many times Walker could say Dy-no-mite.
"His thing was one dy-no-mite a show, that's it," said Walker.
Back then, Walker was pals with a struggling young comedian named Jay Leno. He even talked Norman Lear into having Leno appear with him on Good Times in 1976.
Walker said, "You know, I would always say to Norman Lear, I'd say, 'How about Jay Leno? He's funny! He's funny! He's funny!' "
Walker actually hired Leno to write jokes for him. Another unknown young comic named David Letterman also wrote jokes for Walker's stand-up act.
"David Letterman has been nothing but great to me. As a friend, he puts me on. Whereas Jay will tell us, the network says you're too old and we can't bring you on because people will tune out."
Walker says he doesn't mind that he'll forever be known for that famous catch phrase.
Walker said, "My friend had a line he'd say, 'Your obituary is gonna read; The day the dy-no-mite fizzled.' And that's really what's going to happen. "
