Hard to believe it, but Viagra turns 19 today! The erectile drug gained FDA approval in 1998, and flaccid penises everywhere have never been the same. Originally developed as a heart drug, its famous penis-stiffening side-effect was seen for the money-maker it turned out to be. Oddly, the drug has the opposite effect on the heart -- the drug makes calcified heart chambers more elastic. Our Testicle offers his giant Viagra a giant birthday hug!
