I have these on t-shirts: I'm not mean, you're just a sissy. Flirt harder, I'm a scientist. Eat more krayons. Cats aren't clean, they're just covered with cat spit.
I was at the Ballyshannon Music Festival in Donegal, Ireland in 2002 and there was this guy standing in front of me holding a pint of Guiness and on the back of his t-shirt it said; "I SURVIVED A CATFOOD SANDWICH."
I wear a T-shirt I bought in a shopping mall in West Va. that has Ward and June Cleaver and it says Ward you were awfull hard on the Beaver last night....
I have "Don't be a pussy" with a big kitty on it.. and "Oh shit! It's snowing" in green camouflage
Edited to add... my friend has a shirt that says "The floggings will continue until morale improves" and when he wears that shirt, I shiver (in a good way, hehehe)
This shirt was designed to distract girls while I look at their chests. Front: Do NOT Piss Off The Medic. Back: I Control The Meds On This Rig. If I throw a stick will you leave? Sop talking to my breasts, you will not be meeting them.
I saw a t-shirt at a biker convention that said "Home Grown, Not Silicone" on it. I need that one but it was too small of a size. I also own one that has a road sign that signals a "turn", and has "me on" beside it. I got it for free when I sold my books back to a bookstore after classes this term. I love it!
I still like my "Emo makes me angry" shirt that I got for my man (neither of us is very fond of emo, but he hates it so I had a shirt specially made for him).
I also have one from a DKM tour that says "Kiss me, I'm shit-faced" on it
