Not that funny overall. Someone arranged the letters to read "WRUNCH CRAP" which doesn't display a lot of creativity on their part, but it's easy humor like a fart joke. Sure it's lame, but sometimes you giggle anyway.
OK, this is a little more my speed in that the humor is deceptive. I know it's not jump out at you funny, but lets think about its elements. 1) These are regular wheel covers on a Malibu, 2) the owner was not happy with the simulated aluminum finish of said wheel cover, 3) they decided to spruce up the look and spray painted them black. Maybe because black is a bad ass color and if there is any car that screams "Watch out, I may start trouble!" it's a Chevy Malibu. But best of all is 4) they monogrammed their hubcap. Is the "M" for Malibu?
This gem we found while driving back from vacation this year. Moments like this are exactly why I carry my camera everywhere. Panty Dropper. That's not a name you can just start off with. Your jacked up muddin' truck can't start on the name equivalent of level 11. Maybe it began as Big Red or Mud Bug or some other lame name that I would call it 'cause I'm a girl (An aside: my husband just suggested Mud Butt). Then, I imagine, the owner started getting some attention from the ladies. Maybe he did pretty well in them mud bogs and began getting a second look from the fairer sex. Maybe he had too many Bud Lights and thought his truck was so masculine that at the mere sight and sound of it, panties lost their elastic hold on the waists of their wearers and dropped to the ground in a display of awesomeness. I would say that my panties didn't even flutter so maybe he's just a douche.
