(Removed my question, saw the Recap was already up).
It was a decent episode, I liked their reaction to watching Chase's performance on TV (including his heavy Aussie accent). Before the reveal that he was going to be on TV, I thought he was getting his nails done because he was getting married and was keeping it hidden from House.
Sure, some guys get their nails done... but if it's a rare/oddthing for the person(like in Chase's case) then it's usually for a big deal like a Senior Prom or wedding or something... appearing on TV (in a TV) didn't occur to me.
