Seen this morning on a truck: "CAUTION: BLIND MAN DRIVING".
Apparently JoDee and I didn't get the full joke, though. Here's the rest of it:
I saw this on the back of a van in Rochester:
CAUTION: BLIND MAN DRIVING
On the side of the van (after I passed it to check out the driver):
ROCHESTER VENETIAN BLIND CO.
Har har har.
