The best one we ever pulled was to take a mounted deer head and stick it behind the outhouse. It looked like the deer was laying there with his head sticking out. It was a monster 10 point. The next guy who had to take a crap just about went in his pants. Can you imagine having to go to the bathroom right after eating bacon eggs and sausage for breakfast only to realize that you have to remain completely motionless half way there so you don't scare the "huge"buck that is bedded down behing the outhouse. We laughed so hard but after 15 minutes of squeezing his cheeks together I don't think he could hold it any longer, so he ran for it. I think he was pretty pissed after he realized that the deer didn't move an inch.
