How about the shaving cream in the palm of a sleeping person. You don't have to tickle their nose with a feather for an immediate reaction. Just put it there and tip toe away. They will tell you about it later.

I did it once to a friend. I put it in his hand and left before I died laughing

He told me later that it was bad enough that I had put it all over his face, but inside his pants was too much!!!!!!!!

In the pants ...way to funny .

I'll remember the next time to leave.
Thanks
when I was about 14,I spent the night with one of my friends and we did the shaving cream thing to his dad

,but we stayed to watch, with the feather in my hand I was so

busted.When he caught me, I wore a whole can of shaving cream.To this day a shaving can makes me cringe.
