Let's start with the basics: do not ever do something like this. We've all seen hidden-camera pranks involving fake spiders and jumping out from behind couches, but this guy takes it way too far.

When his girlfriend and her two friends come home from work, this guy leaps out of the bedroom in a ski mask holding their valuables. The fake robber act completely freaks out the three girls as the boyfriend chases them down with his camera for reaction shots. Much crying ensues. (We don't think that's what he intended.)

Let's just say we have a feeling this guy is still apologizing to his girlfriend for this terrifying prank. That is, if he still has a girlfriend.
