That One Time Fall Out Boy Was Panic! At The Disco For Halloween

Every halloween, we look towards celebrities to go all out with their costume ideas. They take parties and pranks to another level for good or for worse. Although we've seen some pretty impressive costumes this Halloween season, nothing will top Fall Out Boy.

The time was 2007. Both they and Panic! At The Disco are some of the biggest alternative bands around. Fall Out Boy was scheduled to play at the Fillmore in Miami when it was announced that Pete Wentz was injured. Before fans could get upset they're informed Panic! At The Disco was stepping in. Fall Out Boy in full Panic! attire go on to cover 'I Win Sins Not Tragedies'. Execution was flawless.
