Yep, post 'em here. I'll post a few I've seen that have made me laugh
"My dog is smarter than your honor student"
"I like poetry, long walks on the beach, and poking dead things with a stick"
"My child would have been an honor student..... but I had an abortion!"
"Stop honking, I'm reloading"
<insert a picture of a mutated frog w/ a hand giving the middle finger for an eye>
"Practice abstinence in 2004, no Bush or Dick."
"Hug a tree, kill a Bush."
and on my car:
"</BUSH>"
