That reminds me of a joke I played on one of my travel companions, and it backfired. On a trip there years ago when I was in art school several of us were walking in Paris during the evening, and Carole was complaining about the insane amount of dog merde on the pavements. I pretended to spot one as she was about to squish it and suddenly grabbed her and yelled, "DON'T STEP THERE!" She ended up screaming out loud in a startle right into my ear. The scream was heard for blocks, and my ear was buzzing for an hour after that.
