It’s kinda rude, but it’s still pretty funny.
Must say that’s not a prank, it’s just being a jerk, but it’s freaking hilarious!
Also it says in description that they gave each person that was pied towels to wipe the whip cream off, and money for dry cleaning. Even if they did pay for their dry cleaning and gave them towels doesn’t justify the fact that they probably ruined all those peoples days.
Pieing that guy in the suit is just low and simply antisocial behaviour, but on the other hand pieing spiderman is awesome!
