I've been to only one haunted house, and I thought it was okay. I don't easily scare, so I usually find the "scary" stuff foolish.
My one experience entail a huge laugh, though! My four friends and I had dressed in black and painted our faces black and white before going into the haunted house. There was a point where we were on the second floor, walking around the perimeter of a room with black lights and waiting for something to jump out. Before my guy friend who was leading us opened the next door, he turned around and screamed... at me! My mostly white-painted face really stood out and had scared him.
