I was stoned, sleeping round my mate Bens house (he was detoxing, so he didnt get stoned) and after going in the garden for a J, I come back. Ben goes to the loo, and I have the awesomely funny idea of switching the light off in his room, hiding behind the door and shouting 'boo' when he comes back. So, I hide behind the door, light off - and hear the loo flush. Getting ready, the door opens, the light comes on and I jump out from the door and shout 'FREEZE MOTHERFUCKER' at the top of my voice.

It was his dad.

He just looked at me funny, then walked off. Needless to say, Ben thought it was hilarious.
