Mattress store apologizes after hideously offensive 9-11 ad

The owner of a Texas mattress store apologized after associates, without his knowledge or approval, created a mocking 9-11 ad so horribly offensive it's hard to believe it's real.

UPDATE: The store has closed indefinitely

The ad offers various size mattresses for the price of a twin mattress.

"What better way to remember 9-11" than with a mattress sale? the woman in front begins. It gets much worse in a hurry.

The two guys fall into the pile of mattresses, sending them crashing, while the woman in front pretends to scream and signs off saying, "We'll never forget."

The original ad is gone but it lives on in YouTube clips and screen grabs. Here's one user  Jamie Barrientos posted.
