From Maureen Dowd’s recent interview with Jon Stewart and Stephen Colbert:

So it’s impossible to go too far?

STEWART: No, too far is different for every person. I would hope that my sense of humanity prevents me from saying things that are exploitative or so denigrating and derogatory as to be offensive. But I don’t understand how anyone can consider jokes about this stuff worse than the reality of it. We’re not out to provoke. We’re not out to shock. There is no joy in stepping over a line. I don’t think there’s any way to possibly offend in a comedic sense when reality has such a desperate foundation to it.
