What I like about Jimmy Kimmel Live is how the monologue is pretty much like a set you would hear by a comedian at a local comedy club, not really a typical late night yakker's rant. This differentiates the show from every other one and makes tuning in rarely a mistake.
Seeing Manny Pacquiao get such a good reaction was more proof that boxing is still alive and well. Manny was not exactly charismatic, but his awkwardness and lack of English made for an entertaining interview. Fighters are rarely good guests, but I always tune in when they're on, like any fan should.
