From my local supermarket:

Now, this is probably a thing that other people know about, but these "round cubes" are neither "round" nor "cubes." If they were round, but not cubes, that'd be okay. Or if they were cubes, but not round. But this is like calling Fear Factor "must-see television."

But then, I guess "shreads o' meat" doesn't sell cow.

(And, yes, I realize that as far as observational humor goes, this probably rates somewhere between "What's up with white people?" and "Ha ha! He dropped that on his crotch!" But it amused me.)
