Actually, his problem is very serious but he is willing to show us what and how it went wrong by injecting silicon in his penis.
There are probably hundreds and hundreds of men in mid-1990 before Viagra was introduced also injected another FDA-approved medication into their penis. It also caused fibrosis and many other side-effects.
But this man's problems included impotence, fibrosis of the penis, urinary incontinence and fluid around his testicles and possible increased risk of developing cancer !
He is laughing and thinks he is soooo smart to challenge the viewers but he is dying slowly probably of AIDS !
