The best part of The Tonight Show with Conan O’Brien last night was Neil Patrick Harris (How I Met Your Mother) as a guest. I watched it live, which unfortunately meant I also caught some of the band Creed (augh, make them go away forever!). My ears were not happy about THAT. But NPH more than made up for it. Harris is charming even when he talks about The Playboy Mansion and Jason Segal’s uh…manly bits (Forgetting Sarah Marshall references FTW!).
