How about that show "It's a Mad Mad Mad World of Comedians" with many celebrities such as Groucho Marx and the Smothers Brothers?

I loved that Rankin/Bass TV special! I wish they would release it on
DVD ... and also Flip Wilson's two Clerow [his real name] cartoon specials. I'd love to see them again.

There were also several celebrities who appeared on The New Scooby-Doo Movies, including Don Knotts, Phyllis Diller, Sandy Duncan, Jonathan Winters, Jerry Reed, Sonny and Cher, Davy Jones, Tim Conway, Don Adams,
Cass Elliot, and Dick Van Dyke.

Lastly, baseball player Willie Mays voiced his cartoon counterpart on a segment of the ABC Saturday Superstar Movie.

Would Woody Allen's comic strip count?

How about that "Life with Louie" cartoon about Louie Anderson?
