Premiered: September 22, 1992, on MTV
Premise: The animated misadventures of MTV's moronic teen `metalheads,' who can't do anything but play air guitar and crack vulgar jokes. Still, they have strong opinions on rock videos, as well as a number of other topics about which they know little, if anything. The dumb-and-dumber duo debuted in 1993, and new episodes ran for some three years. In all, 65 episodes were produced.
