It started because Isaac would always say this stuff like "you know i can't do that, im a lazy mexican" or "you sure you want to leave me alone with your stuff, im a mexican" and so on. At first it was just awkward and kind of "wtf", but after a while it became a thing with that group, we would say that stuff too. But that sort of illustrates the point -- the things that are funny with a core group that knows the back story and the actual intent and meaning of a running gag is different than with strangers.
