Liking celebrities is a funny thing. We don't really know that much about them (at least I don't). Yet when a person plays a character I love on tv, I transfer a not insignificant portion of that love to the actor or actress. As a result, it can always be a bit harrowing when an actor I "love" has their opinion or life exposed in some critical way. Say, if I find out they are a terrible parent, below to a crazy pants church, or support Ron Paul. Stand-up comics are a bit more exposed than most, because they have control over what is in their routine, so it's nice when a stand up comic's routine is close enough to something that I can project as conforming to exactly what I want them to be!
Also, Donald Glover is really funny.
