Why does he seem to have such a large fan base?

Hello? Tiger blood. Winning. What's the mystery?

He was the king! Im a huge fan.

He’s a powerhouse!

Dude lives his live like probably most straight guys would love to. Bangs hot chicks, does insane amounts of drugs and alcohol and hasn't died from it and also, simply doesn't give a fuck about what people think.

Larger than life rep and the show Three and a half men where he more or less plays himself in a suitable for TV manner.
