Basement waterproofing Puns

So my wife and I went to Great Floors looking for tile and generally getting an idea of what we want to finish our basement bathroom and family room with.

The saleswoman points us to this vinyl plank stuff I've never seen before that you just lay down with no glue or anything that is somehow completely waterproof and lifetime guaranteed and all that jazz. She shows us how you need to use a plunger to pry them back up once they are all tight together.

Me. "Wow, I never would have thought this could work.... I'm floored."

In the ensuing groan fest the saleswoman claims to have never heard that one before, I jested that she sounded knowledgeable for someone who obviously hasn't been working in the business very long.
