Fred Berry, from the 1970's sitcom "What's Happening!!". It dealt with the mischief of three African-American teens, Raj, Rerun, Dwayne, living in the Watts area of Los Angeles. Rerun was an overweight and cheery character who wore bright colors, was a great dancer, and was often self depricating: "I can't help it if I'm fat! It runs in my family.". Same genre as "Good Times".
As for you, Rerun, get your fat ass up offa that couch and do something!
Quit dancing around like a fool, Rerun!
A person that you have slept with before, or hooked up with previously.
Jayne: Did you end up sleeping with Danny?
Stacey: I made a decision. No new people from now on. Only reruns.
Stacey: Saw James last night. Gotta love a good rerun.
Jayne: Reruns are always good! New people are just hopeless.
Someone wears the same clothes back to back.

Who are you, Milton Baines?
