Joking steal is as old as jokes themselves,but does that make it ok? Some comedians can make "borrowed" jokes work better than the orginal author and some comedians don't mind giving that joke to someone else. I'm sure doing stand-up night after night,hanging out with other comedians and listening to other's do their sets you could pick up others jokes and not even realize it. Take for instance comedian Otto Peterson from "Otto&George",he was upset at Jay Mohr for just using a phrase that Otto feels like is his. Jay and Otto later squared everything up but it shows how touching comedians can be with their routines.
So is joking stealing a bad thing? Well it depends on if you are the one cashing in on it,or if you are like me and believe if you don't have the talent you shouldn't be the one "make'n bank" on it. Some very well known and well liked stand-up comedians are in fact joke stealers. Dane Cook has long been rumored to be a joke stealer thats one reason he is not well "liked" around a lot of comedy circles. The best case of a joke stealer and just over all douchbag is one Carlos Mencia. Mencia is a pure fruad and is despised thru out most stand-up comedy circles everywhere. Carlos denied for years he stole jokes untill a few things "happened" and he was flat out busted. One,George Lopez has been said to have punched Mencia in the face back stage at a show for stealing his material. Then this happened
