Adventures in T-shirts

Twice a semester, I'm expected to proctor student examinations. That means that I spend 4-5 hours on a Saturday strolling around an auditorium while my students write the midterms and finals. It's a long, boring day. To amuse myself, I read what's written on my students' T-shirts. Here's a sampling of what I read last Saturday:

- I love school
- I'm a tosser
- Delicious Litmus
- Thank you for getting naked
- Happy?
- I see dead people
- A cup of my mind colors
- Mockingbird wish me luck
- The sound of a kiss is not as loud as that of a cannon but it's echo lasts a great deal longer

I would love to know who makes these shirts, and whether or not the students know what they mean...half the time, I sure don't (or wish I didn't!)
