Heh. I also like the "Entropy Happens" one.

I think I need a bumper sticker of that to paste on my office door.

hehe

When I was an undergrad one of our laser labs had a standard warning sign on the door that had been doctored to read:

DO NOT STARE INTO BEAM WITH REMAINING EYE

The version on the shirt is too wordy.

Speaking of geeks, I read Steven "If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?" Wright has a new video/special.

Some more cool t-shirts: thinkgeek.com.

I like "if you're not part of the solution, you're part of the precipitate."

I like the Futurama gag - they go to the track on their day off, and one race finishes in a dead heat. They use an electron microscope to determine the winner, "in a quantum finish."

Farnsworth growls, "No fair! You changed the outcome by measuring it!"

Ha! I didn't see that one Fly!

Laura, Daughter Number Two was the one that turned me on to Thinkgeek. CottonExpressions has some too, my favorite is this one (John was the one who told me here that it was on a t-shirt.

I was always fond of that "If you're not part of the solution, you're part of the precipitate" one.

probably because I spent so many of my undergrad years hearing protestors chant about how if you're not part of the solution, you're part of the problem. (Which always seemed like a dumb argument to me, not to get off topic. You could be absolutely 100% neutral on a situation and not do anything and that would NOT make you part of the problem, thankyouverymuch.)

Daughter Number Two likes that one, too. Hell, so do I.

Amusing trivia about that Steven Wright line ("if you're in a spaceship..."): That, in fact, is exactly the thought experiment that led Einstein to develop the Special Theory of Relativity.

I always liked "There is no such thing as gravity, the eath just sucks!"

Ummmm......that should be "earth", not "eath", although that sucks as well.

Great one, Jeff!
