I'm not sure what to think here.
On one hand it seems obvious from the video that Carlos/Ned lifted at least one joke - the "Who will build the Superwall" schtick. Watching the way these other guys go after him, that's apparently a bad thing.
On the other hand, I watched the episode from "Mind of Mencia" in which Carlos did the joke and he spun off this whole other set of jokes from it. Good bit too and seemingly all original except for the first joke.
So is the lesson here that you can't use anyone else's material or you have to ask for permission or if you use it don't let anyone catch you?
Inquiring minds want to know...
