I edited my above-comment to better incorporate multiple comedian's POV on off-color humor ("x-isms," to use PG's terminology)

>Where was the joke?

If any comedian's attempt at any "joke," however tactless, led to any two+ people sitting down and having discussion of real-world realities... then I think the jokester has exceled professionally (honestly I haven't seen this Kimmel clip; I always just remember him as black-face-guy from 90s Comedy Central™ — which was as appropriate/funny/accepted as Downey in Tropic Thunder).

So in this particular case, Kimmel continues his professionalism as Jester.
