I thought it would be fun to create a thread of our favorite retail whoppers -- in case that word doesn't travel in our non-U.S. circles, a "whopper" is a ridiculously big lie. One-sentence claims that everyone knows couldn't possibly be true, and yet we continue to hope...

Here's perhaps the all-time classic:

"One size fits all"

(To which we all say BWAH ha ha ha...)

What else?
