User blog:MrTyeDye/I want to get my brother hooked on TLH; what's the first episode I should show him?

My brother knows I'm a huge TLH fan, and he said he wants me to show him an episode this weekend, just so he can see what all the fuss is about. What should I start with?

I'm thinking of either "Left in the Dark" (what better place to start than at the beginning) or "Undie Pressure" (could make for a nice general introduction to the cast). What do you think?
