Nathan Fillion on 'Conan'

I know what you crazy kids like: Nathan Fillion.

If you don't know who I'm talking about (or you don't agree) you don't know what you're missing (a soul?).

He was brilliant in 'Firefly', but personally I enjoy 'Castle' even more (I'll probably get hate mail now. I said I like 'Firefly', okay?).

Anyway, 'Castle' was a repeat this week (see my rant about midseason hiatus if you're unsure how I felt about that), but Nathan Fillion did make an appearance on 'Conan' and 'Good Morning America'. For those of you who missed it, enjoy:
