Law & Order: Special Letters Unit

Sesame Street does Law & Order. The official Sesame Street website describes it as a parody, but apparently at least some of the actors are participating, Dick Wolf is using it to sell the real L&O to reporters and little kids, and it seems to be "authorized" even though it makes fun of the signature chunk-chunk. Copyright owners won't authorize parody, eh? (Or perhaps that should be "A?")
