Greys Anatomy is usually about the girls - especially the "twisted sisters" who somehow manage to make everything so complicated.
This episode focussed solely on the boys - aside from brief appearances by Kepner and Bailey none of the girls were in it. It gave us a chance to see what made the boys tick. Men don't like discussing feelings but banging nails into wood gives them an outlet for their frustrations.
I loved the Mayfield Room 22 excuse - Brilliant!!! We need more comedy like that
