usually I'll just jump slightly and swear but one time when I was like 12 I went through a haunted house thing with my family and at the very end this dude popped out of an old refrigerator and scared the bajesus out of me but it ended bad for him cause I had half a bottle of pop in my hand and when he jumped out to scare me I instinctively smacked him in the face with it and like broke his nose. The next year there was a sign outside the haunted house that said "No drinks allowed inside" which made me feel fairly proud, oddly.
