Bumperstickers can be quiet statements of personal effort (like the recovery icons), political statements, either direct or sarcastic (like Keep Davis Boring), or just witty amusements to publicly comment on the world.
Bumper Stickers/Signs
They can send me to college, but they can't make me think
I'll start off - I saw a sticker the other night on someone's car that read, "Don't Drink and Park. Accidents Cause People."
"Save a tree. Eat a beaver."
"Alcohol and calculus don't mix - never drink and derive"
"Born okay the first time."
"This aggression will not stand, man." — Seen on the back of an bicycle infant seat on E Street near Espresso Roma. 2005-11-4
In the back room of In-N-Out, Davis. Why does this door even exist, then?!
"Dip me in honey and throw me to the lesbians" -seen in South Davis
"Draft the SUV Drivers First!"
"The only Bush I trust is my own"
"This car is a status symbol. It symbolizes that I am poor." -seen on a 90's convertible cabriolet

"Forty-Six & Two Are Just Ahead of Me" - seen on a Honda Civic on campus.
"MetalOn" - my friend Danny's car (I'll get a picture soon).
JabberWokky had California plates R H P S (with spaces and centered), and briefly drove around Davis (okay, nearly a year) with Florida plates "RKY HROR".

Other funny things seen in Davis
Found at the South Davis Rite-Aid. I might rejoice if I had gone some time without, too.
