While watching this compilation of people pranking their sleeping friends and relatives, one thing becomes abundantly clear: you can't trust anyone. These may be some of the worst pranks we've ever seen.
Mouse traps? Flame throwers? Ear-rupturing explosions? It's all fun and games until someone loses a finger... or one of their five senses. Although we do have to give the truck guy points for most creative way to end a marriage.
Note: Watch out for some totally understandable not-safe-for-work language.
