Bad casting
After watching Happy Endings, I am finding it really REALLY hard to think of Stosh as some womanizing, hot, douche bag. It just doesn't fit at all. The guy that played the gay guy with no job from Happy Endings made a really nice transition into a physician on The Mindy Project, but I cannot wrap my head around Stosh's character.
It also makes no sense that some of these characters just met and are now BFFs.
