*Post includes possible minor spoiler for upcoming episode Wingmen*
Yeah I am still laughing and think its so sodding brilliant I had to know more. And give it its own thread here in the HBO section. Can also read the Art Garfunkel interview on the forum here
So, here is what I found out about where Garfunkling came from
Thanks to a certain someone for the insight
It was apparently an improv of Jemaine's in that scene with Kristen.
There was a scene in Wingmen where they talked about 'Jemaining' (apparently may not have made the final cut) and it had been shot the week before (they shoot out of order) and it is thought that may have triggered it. The rest was the usual JC/BM/JB combination.
