Because Vince Russo.
He thought that introducing erectile dysfunction pills to wrestling is such a great idea that they even had an angle based on the drug. And a match.
Of course, this is Vince Russo we're talking about, so he's bound to ruin everything.
The Franchise and Billy Kidman had a match because Kidman showed a part of a sex tape Shane Douglas (Franchise) didn't want us to see...his shortcomings. That fueled fire to this match.
And it was horrible.
I grew up watching wrestling during the Attitude Era, where pretty much everything that is edgy and borderline objectionable was neutralized by the fact that it was actually entertaining (Mae Young's hand notwithstanding...tho, the WWE did have a nice touch following up on that angle on RAW 1000). With women dressing like...*that* and everything you can think of that's violent and adult content, it made for actually good TV when you book it right. WCW circa 1999/2000, however, is the Attitude Era gone wrong if Vince Russo is in charge, and we all know that Russo ruins everything.
Screw writing this up, all you need to know that it's awful.
