The vehicle owners below deserve a big thank you from everyone for making the world a funnier place, one bumper sticker at a time. Their good sense of humor and hilarious stickers have people at traffic and rest stops giggling.

We all need a good laugh, so for starters:

Class of 1491

This bumper sticker had many eyes rolling to the back of heads, but finish reading the message, and it’s all good for most.

“The world is flat – class of 1491” is a hilarious sticker for science lover. Though the message might go “whoosh” with those who need to hear this the most.
