A old 7th level video game?

Years ago i had a cd that had a bunch of old 7th level video games, including the a Monty python game, and Tuneland, The Universe According to Virgil Reality, and a few others. One was a pong like game with floating heads that made a funny sound when you hit them, sorry for the dicey information, but it was years ago and i dont really remember much, I was wondering if anyone new the name of that pong like game. that would be great
