Behold! I present to you another pathetic TV show:

Cop Rock

quoted from imdb:
"In what must have been one of the shortest lived series on network television, "Cop Rock" was part "Real Stories of the Highway Patrol" and part "Sound of Music". After chasing down a criminal, the force would take to the street for an organized dance number, then haul the guy back to HQ."

all those involved in this show should have been blacklisted

edited to add: check youtube, there are some clips on there
