I love this episode, deeply and truly. The addition of Dr. Kevin Casey (Michael J. Fox) gives this episode another layer. Kevin becomes the shrink around the hospital, helping everybody out with their individual problems. Turk asks J.D. to be the best man at his wedding, and we are really shown on this episode how close J.D. and Turk really are. Then, when J.D. hears a message from Turks brother, he finds out that Turk asked his brother to be his best man before he asked J.D. This leads to J.D. questioning his friendship with Turk. Meanwhile, Kevin struggles with using The Janitors roof toilet, and Elliot struggles with completing a simple medical procedure that she shouldve mastered years ago.
It all comes to a head when both Kevin and Elliot use The Janitors rooftop Epiphany Toilet. Kevin is able to get over his fear of the germs, and Elliot gets her epiphany and is suddenly able to complete the procedure. Meanwhile, Turk and J.D. sit outside on Turks car and have a memorable heart-to-heart about the wedding.
This episode is quoteable, memorable, and it leaves you just feeling good all over. 10/10.
