It's been a while, so they're gone, but a couple of memorable ones I've seen are:

THREE LEGGED CAMERA TRIPOD. (As opposed to what? A FOUR legged tripod?!?)

MEAT RABBITS.

We did ten minutes here at the shop on that one. As in you can't go outside without being armed with a gun because of the dangerous, marauding, carnivorous, meat rabbits roaming around. The ad was of course referring to rabbits to be butchered and cooked, but the headline does bring up funny visuals.
