Schaub is the luckiest guy in MMA history: ended up on one of the weakest TUF's ever, with a bunch of green noobs (Meathead), Kimbo and Roy Nelson, then came a very mediocre UFC career, the single most embarrassing and humiliating grappling match ever, and then somehow serendipitously became friends with Rogan (btw, I wouldn't be surprised if Rogan was Bi like CoGar, and that is the prometheus of their relationship).
I also wonder if somehow Rogan had remorse for verbally castrating Schaub publicly and pulled many strings behind the scenes to atone and make it up to Schaub. It stands to reason that Schaub, who has the IQ of a Grapefruit, fell in to all these shows. Maybe it is a Trump type thing, where he appeals to the lowest common denominator with all his talk of penises, which sounds just like a 17 year old closeted gay jock, who likes taking showers after football practice with other men and making jokes and touching about everyone's penis.
