The best sticker i have seen was on a scion tc front wind sheild it said "If you can read this Please Flip Me Over" It was put on so that it was upside down.

To be honest we put it on the car as a joke because he fliped his first car.

 

If anyone cares i still have two of these left in silver
9x12

 

This almost made me **** myself!

My favorites are ...

Mean people suck
Nice people swallow

 

Got one better.

Seen on the back of a Scion XB "Youve just been passed by a toaster!"

And on my boddy's motorcycle "in case of water landing, seat can be used as flotation device"
(he crashed his first bike into a river and we had to fish him out)

 

save the ta ta's takes all you cant beat *****...

 

i saw that one on a ricer on Rt 3 yesterday, funny as hell

 

The one on the back window of my truck says "Eating Fords, ****ting Chevys"

 

I have a calvin pissing on a chev on my back window.

 

Here is a great one.
