Alright you mentors, don't just sit there and pretend you're not old enough to remember.
George Burns was on a radio show (yeah, they used to have radio shows before TV) "Burns and Allen" with his wife Gracie Allen. It later came to TV.

He also starred in the movie "Oh God" with John Denver (he played God, please don't ask who John Denver is or I'll feel REALLY old). He did alot of comedy shows even when he was much older (he died at age 100 and performed almost his entire life).
