Laff-A-Lympics

This Hanna-Barbera series from the 1970s was a Saturday Morning Cartoon version of ABC's Battle of the Network Stars. The three teams were:

the Yogi Yahooeys, a team of funny animals from Hanna-Barbera's golden age (with the exception of Grape Ape, who was the only post-1962 character in the lineup), led by Yogi Bear and Boo Boo;

the Scooby Doobies, a team of heroes and Meddling Kids from Hanna-Barbera's more recent shows, led by Scooby-Doo and Shaggy;

and the Really Rottens, a team of cheaters led by Mumbly and Dread Baron.

This series provides examples of:

 * The Bad Guy Wins: The Really Rottens win in "New York and Turkey" and "Morocco and Washington. D.C."
 * The Cameo:
 * Fred Flintstone, Barney Rubble and Jabberjaw are recurring guest stars
 * Peter Potamus and Ranger Smith both show up once each.
 * Cartoon Physics: At one point the Rottens were in a skiing event and when they pass Huckleberry lazing in an armchair on skis, they pick him up and pass him back to one another before putting him back. Somehow Huckleberry's skiing armchair stays at the same speed and the Rottens pass it.
 * Color-Coded Characters: The competitors wear their team shirts over their normal attire (where applicable). The YYs wear red uniforms, the SDs are blue, and the RRs are green.
 * In Brazil, shirts like that are used as admission tickets to some Carnaval parties. They're called abadás. It is unclear whether Laff-a-Lympics was the inspiration for the scheme, but one Brazilian troper definitely doesn't remember such use from before the show's time.
 * The Smurfette Principle: Cindy Bear is the only female member of the Yogi Yahooeys.
