Once upon a time the firefighters in our town used to do a haunted house every year. My uncle was a firefighter and we all went one year. I am known for my tendency to swing when fight or flight reflexes kick in, and at the ripe old age of 15, I hauled off and slugged a clown who leapt out from behind a door to scare us.
So long story short: I don't go to haunted houses as an adult because I once punched a firefighter in the face.
I might make a great Ghostbuster though.
