5 Seconds of Summer can pull out a prank or two if need be. When their album came out, they dressed up as Target employees and forced their LP onto unsuspecting customers. But now that they're on their Rock Out With Your Socks Out Tour in Europe, they have a few tricks up their sleeve.

Exhibit A: Why is there bread all over this guitar?

Well, Michael, Calum, Luke and Ashton decided to pull a fast one on their tourmates (and label signees) Hey Violet by whipping out a loaf and plastering their friends' guitars with its slices.

"Well played, @5SOS," drummer Nia Lovelis wrote on Twitter, showing off the "damage." Apparently, this is the second out of three pranks. There's more to come.

Not only did the guys cover their instruments in a delicious, oatmealy, whole-grain bread -- they overturned furniture, too. Good one, guys. Let's see what you've really got.

I mean, I've heard about breading cats. But breading guitars? This is something else.
