Tracy Morgan won over many with his performance as Tracy Jordan on the now dearly departed 30 Rock, but, as many comics have shown, it only takes one incident to tarnish your rep. In Morgan’s case, a bit during a stand-up performance in Nashville turned ugly when he launched into a homophobic rant, where he claimed that if he had a son who was gay, he’d stab him.

Though he apologized and poked fun at the incident in a subsequent episode of 30 Rock, it remains a massive blemish on his career.
