Peace, Love and Understanding is the second pilot episode of Beavis and Butt-head, after "Frog Baseball". Like creator Mike Judge's other early short cartoons, it was funded by Spike and Mike and shown on MTV's Liquid Television in the early 1990s. Mike Judge stated in an interview that he heavily disliked this particular episode, along with the season 1 episode "Give Blood" which were both conceived on the same day.
After sniffing glue, Beavis and Butt-head see a commercial on TV for the "All Star Monster Truck Thrashathon". They go to the monster truck rally, where a folk singer, David Van Driessen sings and gets run over by a monster truck. (Van Driessen would re-emerge in later episodes as Beavis and Butt-head's teacher.) The monster truck then goes out of control and hits a row of port-a-potties, releasing and angering Sterculius, the Roman god of feces. Sterculius goes up into the sky and the arena gets covered in poop. Then, mocking the ending of Frog Baseball, the ending shows To be discontinued with the credits following.
The beginning of the episode where Beavis and Butt-head sniff glue and make racist remarks about the Tom Vu-esque informercial spokesman was later edited out by MTV, along with a shot of an audience member giving Mr. Van Driessen the finger.
