"They all say "I'm bigger" or it got bigger."

If they've got commercials that say that I haven't seen them yet. Even without saying what got bigger, I think they'd be leaving themselves open to having to prove that something will get bigger if you take it. I don't know how effective they are at selling the stuff, but I think the commercials are brilliant in the way they simply use suggestive statements without really saying anything. I'm assuming the only benefit to the product is from whatever placebo effect it might have (which may actually be effective for many cases of impotence, but  I don't imagine it will make anthing bigger, except perhaps your ego or self confidence), but the number of commercials suggest that they have a huge advertising budget.  I can only assume such a budget comes from huge sales.
