Fire Marshall Bill
Someone can correct me if I'm wrong, but I believe this aired during halftime of the Superbowl back in 1992:
"Oh the humanity! Hahahahahahahahaha!!"
I don't know what made me think of this, but Jim Carrey's Fire Marshall Bill character suddenly popped into my head. The continuing theme/gag of the character was that he was constantly warning others about extremely unheard of (or at least implausible) hazards, but he would end up causing explosions and fires himself.
I remembered something sad about that particular show, too: at the close of this episode, which was broadcast live, all the cast of In Living Color were gathered together to bid the audience thanks and goodbye, and Sam Kinison screamed, "I'd just like to say I'm really sorry I bet on Buffalo! Aaauugghhh!! Aaaugghhh!!!" It was one of his last appearances on television.
