So Howard is going on Kimmel on Friday. Friday is historically the lowest rated day for late night talk shows and where they throw lesser guests (sometimes friends of the host who are not big ratings getters but the host use their clout to have them on). Letterman bumped Howard to Friday for Jennifer Lawrence the second to last time Howard was on. The last time was obviously Letterman's swan song and he didn't care about ratings at that point. But if Howard cannot get on a good night for Kimmel especially one a NY centric week, it is clear that the late night shows know Howard has no ratings juice.
