try this one for size: im driving happily along in my girlfriends little hyundai on the 4th of july, just got done picking up groceries for a big barbeque we're having. all the sudden, guess who's behind me with the lights on? yup, the boys in blue.

officer: do you know what im pulling you over for sir?
me: no, not at all.
officer: your plates have been expired since february...
me: (i'm now laughing in disbelief) well officer, as much as I love my girlfriend, she often perplexes me with such mind bending stupidity that i'm actually not surprised she hasn't changed her plates 6 months after they've been expired! i will have the plates renewed tomorrow sir.
