A few guys are on stage in various states of undress, having just got out of the shower or changing into/out of sports gear when one starts whistling the introduction to the my little pony theme. 

The man next to him stops, looks at him for a moment and starts humming along, after a short while they are all humming along and burst into the main theme of My Little Pony in deep voices. They finish in a tableaux of friendship and magic..
