Comedy is extremely subjective. My criteria for whom I think is funny is to identify the person who has me practically unable to breathe with tears running down my face before he's finished with his set - and by that standard, both John and Gary have both been very successful. While Alonzo does not leave me absolutely helpless with laughter, he creates a generous and steady display of very hearty guffaws. This is as opposed to Kathleen, who produced a good supply of chuckles, Jay, who got a few sympathetic snickers, and Tammy, whom I stared at in cold silence.
Yes, I think we got precisely the right final three. My vote will be based on my impression of their final set, and I have no problem with either cookie jokes or jokes that discuss (maturely) how the races or the genders interact with each other. Who's got me rolling is my only criteria.
