I'm pretty sure Alonzo, along with the other two, have toned down their material for prime-time TV. Maybe one of the benchmarks for a great comic is that they can do raunchy material (like all the comics Krom listed) and still enjoy huge success with a wide cross-section of the general public. IMO, Alonzo's polish and delivery saves his jokes from being offensive. Corey, on the other hand, DID offend me.
Having said that, Alonzo wasn't that great last night. Not quite as *on* as I'd expected, although I did laugh at the "taking one for the team" and the purse jokes. I really thought John Heffron was the clear winner last night, he had me He's really grown on me during his last couple of sets...although I suppose part of what I find so hilarious about his material is that I'm thirtysomething and married with kids, so I "get" it.
Two votes for Heffron from me, and one for Gary, because I've liked him since day one and I really love the cookie jokes.
