There are a few things Dana does to keep things pure and avoid corruption:

1. He drinks nothing but liquor, Coca-Cola and bottled water, because the tap water in Las Vegas has been fluoridated by unwitting dupes in a Communist plot.

2. He does not avoid women, but he does deny them his essence.

3. He does not allow foreign substances to be added to his precious bodily fluids.

Other than that, the UFC is careful to connect itself with only the most reputable and corruption-free businesses and industries, starting with Las Vegas casinos. This avoids the appearance that the UFC, like PRIDE, could ever be tied to organized crime organizations, because Las Vegas and the casinos in particular are so clearly off-limits to such gangsters and riff-raff.
