Saw Cho a year ago. Most of his set has been shared in clips like the one above. That is, seems to be going through the motions. Chris Petersen 2019. That said its still funny after 20 times.
Jo Koy's earlier stuff is great. His first special he self produced and filmed in Seattle there are still things I quote weekly about that. Mostly about how his mom pronounces his name, and Muckleshoot. He's probably a bit like Manny Pacquiau and Jollibee where he's propped up a bit by the substantial number Pill-i-pino Americans. Pinoy! His relationship with Chelsea Handler seemed a bit clout chasing.
Sometimes comedians run out of material as well, or their fame makes it tougher to relate to the common audience member. Saw Gabriel Iglesias at the Puyallup Fair (for free) and his whole bit was about how famous and wealthy he is. Laughs were minimal.
