Physics: It's the Law tee shirt on high quality cotton tees for men and women Max Planck t-shirt on high quality cotton tees for men, women, and youth

Well, would you tell him?
It's hard enough for a Tee Rex to get dressed in the morning, what with the little tiny arms and all. But when he can't tuck in his shirt tag, I wouldn't bother saying anything. The arms are short, but they're lethal.

Mobius cartoon t-shirt for geeks from Tees For Your Head Recalculating Geeky Tee Shirt for mathematicians or GPS users, from Tees For Your Head
The dating world can be tough no matter what your shape, and Mobius can't seem to get oriented as he makes the rounds. Maybe he could be a little less one-sided in his approach, but even thinking about being less twisted makes him feel edgy. Even though we're on a roll, we'll just stop the puns RIGHT THERE. This design was inspired by Katherine, our GPS unit. When she (do they all have women's voices?) says "recalculating," her voice sometimes gets a little shaky and for a moment she sounds like the late and wonderful Katherine Hepburn. She (our GPS, that is) also sounds...<more>

Not t tee shirt on high quality cotton tees for geeky t-shirt-wearing men, women, and youth from Tees For Your Head Feel the Love Braille tee shirt on high quality cotton tees for men, women, and youth
What's this? Why, a Liar's Paradox tee shirt, of course. Such logic beasts tie minds in knots, which you could also do with this tee, taking the teaze even further. This sentence is false. Get in touch with your friends. It's up to you whether you want to preemptively blurt out the translation, or invite people to see if they can figure out what your tee shirt says.
