It's always nice when a stand-up comedian hosts Saturday Night Live because the monologue is actually a monologue.
It's the biggest audience any comedian will ever have to lay down their material, and they're not going to waste the opportunity by doing a bit with cast members.
Since stand-ups tend to be controversial by nature, it's not surprising that they often use these five-ten hallowed minutes in front of a live audience to cross a few lines.
Earlier this season, Chris Rock took on the Boston Marathon bombing and in last night's season finale, Louis C.K. both admitted to being a 'mild racist' (it's the best he could do after being raised in the '70s) and wondered how awesome molesting children must be for child molesters (hint: really awesome).
