True story
Move over Janet Jackson's left nipple, at halftime this year Prince projected his image of himself holding his guitar like a 4 ft. penis with a curly cue symbolizing testicles.

but that wasn't all...

Prince is so old that he had to put a hydrolic system on his guitar to make it squirt liquid out the end of the neck.

ergo the need for the super bowl committee to have him perform behind a sheet in shadow.
