Who doesn’t enjoy a funny bumper sticker? Originally designed by companies to advertise their products and services, bumper stickers are now often a source of entertainment. Bumper stickers have evolved into witty one-liners or funny jokes that provide a few laughs while driving. While they are still used by brands, religious organizations, political parties, and businesses, most bumper stickers on cars are just a bit of fun to liven up the dreary driving experience.

This has caused some controversy over the years, with many bumper stickers containing NSFW language or images that not everybody should be viewing. There was even a court case involving a man who was convicted for having a bumper sticker containing indecent wording, although his sentence was eventually overturned. 

Staying away from anything too controversial, we have collected 20 hilarious bumper stickers that will have you looking twice if you see them out in public.
