Last time I was in a 'haunted house' type attraction with a friend, it was one of those ones where the 'room' looks normal until you enter it, and a sensor triggers a reaction in the scene when you step on a tile or break an invisible laser. She was in the lead (I fell behind trying to put my camera back in its bag). We got halfway through the first room, and she tripped the trap (a dead body sitting up in a bed)... she SHRIEKED (not unlike Judy in the movie) and back-pedalled into me. Two rooms later she told me to go first and we ended up in a position similar to Judy and Nick here... which was rather awkward for me, being a guy (she wasn't my girlfriend).
