My club back in high school did a haunted house for a showcase event. We were working with cardboard and trash bags for decor, due to the limited budget. But it was still pretty cool even though some of the older visitors ended up laughing. To our credit, we had to stop the walk halfway because some people were crying (not from laughing. Fear, mind you.).
I was the thing in the cupboard which reaches out for you when you get too close. A bodgeyman of sorts. We trashed an old metal cupboard for this and it was stuffy and uncomfortable.
If I could do it again, I would. But this time, with more spooks. =p
