I just realized that one of the reasons why Paul Rudd is so likable is because he doesn't half-ass any of his roles. (At least as far as I've seen.) Whether it's a movie role, a sketch, or that running gag from his Conan interviews, he always seems to invest 100% into it.
The same can't be said about other celebrities. For example, Will Arnett hosted Minecon Earth a couple of days ago, and through most of it he looked like he wanted to die. [Like in this late night TV sketch that happened towards the end of the event.](https://youtu.be/A_Z3AokMwWI?t=8231
) The musical number that immediately followed also shows Arnett giving next to zero fucks.
