I found some really funny bumper stickers . . . .
"The difference between genius and stupidity is that genius has its limits."
"If you don't like the way I drive - get off the sidewalk."
"Forget about world peace . .Visualise your turn signal blinking!"
"Next time you think your perfect . . Try walking on water!"
"I'm not a complete idiot, some parts are missing."
"i don't suffer from insanity, I enjoy every minute of it!"
Anyone got any other good ones? :)
