Panic! At The Disco Prank: Rock Band Trolls Crowd On April Fools' Day [VIDEO]

Panic! At The Disco probably pulled the greatest emo prank of all time during their performance at AT&T's NCAA March Madness Music Festival.

Knowing that it's April Fools' Day, the rock band started playing Fall Out Boy's Sugar, We're Going Down. Then, lead vocalist Brendon Urie ended their charade with a hilarious, "April Fools motherf*ckers."

Watch their funny video below.
