I have to admit, I made myself laugh today.
I was coming out of the grocery store and a guy had just parked and was getting out of his car.
Along the side of his car, from the back tire to about halfway along the back door (4-door), a bird had crapped mid-flight, leaving an undulating line of brownish-greenish-whiteish spots, reminiscent of bullet holes.
"Looks like you're the victim of a drive-by sh!tting," i said when I walked by.
You should never laugh at your own jokes, but I have to say, I was still laughing 10 minutes later.
