A comic book series on the Piranha Press imprint of DC Comics 1989-1992. The artist was Dan Sweetman and Dave Louapre was the author. They were great, there was an incredible one, my favorite, which was about a town of lemmings having a picnic, pretty as you please, giving out baseball trophies and stuff, and then all jumping to their deaths.
Probably the best known ones (relatively speaking) were the two that dealt with evil clowns. The clowns leave the circus with the siamese twins and the bearded lady and drive around in a convertible and get drunk and cause havoc. It's been a while, sorry to be sparse on details. The band Mr. Bungle used a drawing of a clown from the very first issue of B.S.U.C. for an album cover.
