competition: Dumbest thing I did as a kid

When I was 3, I was at adepartment store with my mom. Walking through the racks of clothes, I came upon a curious cord hanging to the ground. I thought it would be fun to pull as hard as I could on the cord! Unfortunately for me, it was connected to a speaker that was up on a shelf for their PA system. It came straight down...onto my head. My prize for pulling the cord? A trip to the hospital.
I've been scared of curtain drawstrings ever since.
