The only reason i have to say i disagree on all those except pryor and maybe cosby is because they are all pretty much done. Eddie Murphy had some of the funniest standup EVER and he just stopped, now he does crappy movies. Chapelle, well he had his show and we all know what happened there, Oprah got on his TV and hijacked his cable !! well thats the theory anyway. Richard pryor, well… he sorta wigged out on crack, lit himself on fire, got MS and died. You left out Chris Rock, John Leguizamo, and George Carlin. Theres a ton more that im forgetting too but you get the point. Old comedians> new ones.
