Shawn was a little out of line as a commentator.
But Earl was ridiculous as a competitor.
While Johnny was running his 140, Earl was waving his arms, yapping to the crowd, complaining about how long Johnny was taking (he wasn't). He was sitting in his chair and jumping up when any ball rattled. Complaining about the pocket sizes by forming his arms into a "V". Then he talked and talked to the audience during his run, mainly complaining about how slow johnny was playing while "making me miserable".
I don't know why the ref or the sponsors would allow this behavior. Earl is an impolite player with terrible manners. Earl is not a gentleman or sportsman.
If you are truly a friend of Earl, why don't you suggest that he work on his sportsmanship? Earl should be a legend - instead, he's disrespected. He seems to know it too - yet, he keeps acting surprised people are rooting against him.
