Nautical People Have Their Ship Together!
I dont have a car right now but i had a bumper sticker that said:
“It doesn’t get any QUEERER than this”
With a Pink background and black letters.
I have one for the local classic rock station (107.7 WRKR), one that just says “SERIAL KILLER” and another one that says “The Little Voices Tell Me You Suck.”
On my old car, I had “Ever Stop to Think … and Forget to Start Again?”

“Sometimes you win. Sometimes you lose. Whatever.”
I have three:
“Honk If Anything Falls Off”
“The Truth Is Out There”
“Mis-Load” [my brother’s band]

“Jepsen 2002”
I’m working for George Jepsen, a candidate for governor of Connecticut. Kick Rowland’s butt out of office!
Militant Agnostic: I don’t know. Neither should you.
I don’t have one yet, but I always wanted to make one that says “Save me Jebus! (From your followers)”
“Another Deadline, Another Miracle”
Just one “NOFX” sticker.

[hijack] George Jepsen wouldn’t happen to have a wife named Judy, and a boy named Elroy, would he? [/hijack]
Sorry…I’ll go sit in the corner now.

My favorite one fell off 
It said " Thank you for not breeding"
My other ones are for radio stations and one that simply says “people suck.”
I have a “Got Steel?” sticker on mine.
(I build robots)
It looks like a Visa card but in place of Visa it says KARMA It’s everywhere you’re going to be.
'Fraid not DE. Wife’s Diana, I’m not sure if he even has kids, let alone what their names are.
“Virginians for Alternatives to the Death Penalty”
Front plate says “Union Made.”
I have one that says “This is my only car”
I had a Darwin Fish until somebody pulled half of it off. I still have the half they didn’t pull off on there and am trying to remember where I bought it
I saw a really good one the other day , it read “Caution: Driver just doesn’t give a shit anymore” 
I NEED that one.
“The Red Elvises
Kick ass Rockenroll from Siberia”
Imagine that.
