Frightening shirts on public transportation.

I wore my Lochness Monster shirt to work the other day. I was hoping to scare people into quitting smoking. I don't know if it worked. I always end up feeling so darn affirming...People did seem, however, pretty intimidated as I rode the bus home that day. I was trying to think about funny things awhile ago, but nothing came to mind right away. What stories should I share with you? Perhaps you can share some with me instead? Did you know this?
