I'll go all deceased since I was gonna say Chapelle, bill burr, and Eddie but i can watch that as needed...
Patrice O'Neal
Redd Foxx
Don Rickles
Joan Rivers
Rickles and Rivers are 2 of the greatest one/two line joke tellers of all time and are absolute machine guns with comedy once they get going. Patrice is maybe the GOAT relationship comedy teller and had so much more to say. Redd Foxx is maybe the best insult comedian ever (ironically Rickles is top tier in this space too) and he'd actually be an absolute superstar today if he was alive.
