Glee: The Spanish Teacher

This was another weird episode, though it was not nearly as good as NCIS. This episode guest starred Ricky Martin, but it wasn't nearly as good as the ones that guest starred Gwenyth Paltrow as a variety of substitute teachers.
Will apparently is having trouble with his skills as a Spanish teacher, never mind that he was wonderful in season 1, but not anymore. So he goes to night school to brush up on his Spanish skills which is where Ricky Martin comes in. After spending some time working as a teeth model, he truly wants to make a difference so he begins teaching. And he is a native speaker so he can speak Spanish perfectly. So Will, determined to win the tenure so he and Emma can always be secure, thus he brings in David (Ricky Martin) and opts to liven up the Glee club by telling them to incorporate Spanish into their songs for the week, sometimes it works, but when it doesn't, it crashes and burns. Will's song, towards the end, is absolutely awful, he dresses as a matador, and Mike and Brittany run after him like bulls. It brought the episode down a letter grade, that's how bad it was.
In other news, Sue wants to have a child. So she asks the guys from the Glee club to provide her sperm for her, she asks Will the same thing. All of them decline, thank goodness. But she finds another donor, so maybe she will end up having a baby. That would be interesting.
Also, Roz Washington the former Olympian, now swim coach, takes over the Cheerios and teaches them some new moves, and Sue hates this, thinking she will take over her job. When finding out the Sue wants a child, Roz bursts out "From who's vagina?" A line later repeated by Santana, to great effect. There were some great lines said by Roz, but Sue had no good comebacks, something that is out of character.
And Rachel, while watching Twilight with Kurt and Mercedes, announces that she and Finn are engaged, and Kurt at least freaks out. He confronts Finn about it afterwards, and begs Finn not to give up on his own future, he should not spend the rest of his life holding Rachel Berry's purse. But Finn says that Rachel is the only good thing going on in his life. But that is all from that plot line, so Finn and Rachel are still engaged. Somehow.
But Mercedes needs to choose between Sam and Shane, her boyfriend. And after talking to Emma, and not speaking to Sam for a week, she decides to walk up to him to spill her guts, Shane walks up and she goes off with him.
Will is cruel to Emma about her pamphlets but then he later apologizes, and after all, she is the one who gets the tenure. And Will is going to become the new history teacher and David will be the new Spanish teacher. So all is right with the world. Grade: B+ but Will's horrid song brings it down to a B-.
