Actually, Bob doesn't have erectile disfunction -- the product is supposed to make a man... uh... bigger.
The FDA won't let you say that without proof, so much like the HeadOn ad, there are no specific claims made in the ad.
Oh, right! I forgot. Male enhancement. Not erectile dysfunction. I asked my husband how that actor could possibly go out in public after those commercials. He said, "At least everyone knows he's big now." LOL!
