Now I sure You've seen the credits of Beavis and Butthead and saw somthing that was out of place or made you say " Hey, I havn't seen that one yet. so I'm refering to episodes that were either advertised on tv but never made to an episode.

there's one where the some old lady in Bondage, not sure what was up with that, annother with the guy asking beavis to pet his Pooky (His Cat) and one where they go to an aquarium and feed balloons to the whales.

please tell me if these exist or I'm just seeing things.

the pokey one they where taking care of a dead bird and went to the vet. old lady one the where going door to door collecting for charity. whale and ballons one the where trying to kill a dolpahin with helium ballons

I'm almost certain the pet his pooky existed.
