This is one that a friend of a friend of mine did to his mom.

This kid was going somewhere with his mom in the car. The kid
was in the back seat, and the mom was driving. It was summer
time, so the kid had the window rolled down.

Anyway, the kid see's this jogger comming up the side of the road,
so he starts motioning to the jogger. The jogger didn't really
know what was going on, but just as the car passed the jogger, the
kid reached out of the window, and whaked the side of the car rather
loudly with his hand. The jogger, getting the idea, dove in the ditch
and acted like he was in great pain (similar to the pain he would
feel, say if he just got hit by a car).

The mother obviously notices the loud noise and see's the dieing
jogger in the ditch, slams on the breaks to see if this poor guy
is dead or not. Naturally she is worried sick.
