Prank Ideas For Videos!

Whats up guys? So i want to ask you, maybe you know some great prank ideas for filming and you can share it with me? Pranks could be social, like talking with people, messing with them. Also could be staged and so on. You know like do vitalyzdtv, prankvsprank, bigdawstv. Maby you can offer to do something unique? I don't want to copy from others. Waiting for ideas :)
