I believe Nathan's buttocks was featured prominently in an episode of Firefly.
I didn't notice that frame when I watched it last time. Meh, I can tell it's the puppet's shtick. It's just some knuckle-dragger plebeian humor inserted into the segment in post production.
I enjoyed the rest of the interview from what I remember.
That brings up a question though. Which television or radio personality would you most want to interview Summer?
For late night talk shows I think maybe Leno and Summer could have good chemistry. but Letterman I remember as being witty and a bit goofy(or was it the other way around?
) That could be a fun interview too.
