"Dressing up as though you are the inanimate Halloween Decor for your lawn. Example: scarecrow, Frankenstein, etc. Be as still as you can. When someone walks by, jump out and scare the heck out of them. Another idea is to lay flat on the lawn, pretending to be in a grave marked with a tombstone. Imagine their surprise when you rise from the dead!"
