i died of laughter when he said "oh guurl oh no she didn't okurrr" i wasn't expecting that at all watching the episode. Also as a Younger fan seeing all these Sutton Foster easter eggs in Smash was so funny (he also played her boyfriend in two episodes of the season 5 of Younger)
The problem is that Glee wanted to find a way to incorporate Mr. Schue into the kids' story lines and it came across.....weird. They should have just kept his life separate from theirs.
