All right, I’m working from home now and no longer need to give even the passing nod to professionalism of wearing shirts without writing on them. Yet I should have something besides pajamas when I venture outside. I would like to see what awesome shirts you have found so I can get them for myself!
Here is my tshirt contribution: I draw pitcures all day tshirt We know what you guys think of designers 
Sometimes, when I’m bored at work, I dig through tshirt sites and see what I can find.
I’ve been glad to purchase these few:
If I run across anymore tonight, I’ll wander back in and post them…

do you want specific t-shirts or just places to find fun t-shirts?
I’ll give you both.
and aw, poor guy 
I am a (close to ) middle aged upper middle class white male who works in a suit and tie when out of the home office.
This is what I wear to my kids soccer games.
I really like the t-shirts at Engrish.com - I am particularly fond of this one . C’mon - join the rock ‘n’ roll!

Buy some of Alley’s amazing hand-printed designs. I have, what, 6 of these now? Gawds I love 'em.
I’ve been eying up this shirt from Geoffrey Chaucer’s Blog - CHAUCER - Funnier than Dante, Prettier than Boccaccio
I also like this one: HOTTE COURTLIE ACCIOUN
Ironically, the model wearing the “I dare you to picture me naked” shirt looks like she has a nice rack.
I like the one in the OP, and I really like the Practical Rabbit ones.
Here is one of mine: Gravity-Free Zone. I wear it to the gym.
Okay, that’s hilarious.
Wow. Just… wow.
Wow, these are some great tshirts. Thanks!
I still want Unca Cecil to sell this one:
(Possibly someone more of a designer that I am could make the ‘Whoosh’ out of phrases like: “When come back, bring pie” “Og Smash” “Hi Opal!” etc.)
Right?! They’re really high-quality shirts, too.
Speaking of, I’m always nervous about buying shirts from places like Café Press, because I don’t know how to tell what’s a good quality T material and what isn’t. Especially in white shirts, because I hate white Ts that you can see through. Anybody got a primer on T-shirt material, and how to tell good from bad?
