I once saw a really beautiful woman wearing a t-shirt that boldly announced, "I'm a virgin"
...on the back it said, "This is an old t-shirt."
"Over the hill?" "what hill? I didn't see any hill"
I saw one a couple of years ago on a guy on his 80's. On the front it said "Trouble is my business" and the back said "and lately business has been good".
A blood stained t-shirt that made it appear as if the wearer had been stabbed several times. It had the caption "I'm okay."
I saw a teenage boy wearing a shirt that said " I got kicked out of cub scouts for eating a brownie"
Splats of bird poop all over and each one had a species attributed to it.
“Don’t show people your happiness! Don’t poison their lives!”
A freshly cracked egg containing a chick the saying was " you'd stink too if you just got laid"
Two pigs having sex saying was "Makin' Bacon"
