This next prank video comes from the same guys who brought us the "Letter B" prank where they went around to strangers sticking a letter B on their back and screaming that the person had a bee on them.

Their latest effort is them going around throwing white balloons at students on a college campus. Of course, the prankees think it's a big ole snowball being hurled at them!

Hilarity ensues until the 1:16 mark when a campus police officer suggests to them that this is not such a good idea.
