Sledge Hammer had the best finale ever. Hammer had to stop a terrorist squad of female bodybuilders let by a crazy aerobics instructor, who had stolen a nuclear bomb and threatened to blow up the whole city. Hammer finds the bomb with only seconds left, and uttering his catch phrase, "Trust me, Doreau. I know what I'm doing," he moves in to disarm the bomb.

Cut to commercial.

After the commercial break, nothing is left of the city except a vast desert with some debris that used to be buildings. In the background, you can hear Hammer's boss yelling, as he does at the end of every episode, "Haaaaaaammmmer!!"

Then to everyone's shock and amazement, the show was picked up for another season and they had to pretend like it didn't happen.
