When I was a kid, two of my friends and I discovered an old cemetery (probably a slave cemetery; I lived in the country in a Southern state) in a clearing in the woods. Many of the graves had settled and sunken in a bit, and all of the markers had crumbled to pieces. Naturally, we didn't tell our parents about the discovery, since we knew they wouldn't let us play there.
Anyway, that year at Halloween, we decided to play a prank on some other kids. So, my friend Michael went to the cemetery, laid in one of the sunken graves and covered himself with leaves, while the other friend and I led the rest of the kids to the cemetery.
Needless to say, the prank worked fabulously. Michael reached up from the grave and grabbed a girl's ankle, and all the kids ran from the woods screaming.
Of course, then our parents found out about the old cemetery and we were all in lots of trouble...
