Sue says, "I'm not an American citizen. I was born in the Panama Canal zone. But I managed to get a passport. And run for office twice." This is a reference to Arizona Senator John McCain, who was born in the Panama Canal Zone and who ran for the presidency of the United States in 2000 and 2008. See more »


Terri says that the Pseudoephedrine products are "simple over the counter" items that you can get in the store with no problem. Actually, the US regulates the sale of pseudoephedrine products, limiting a person to how much they can by in the store. Most stores scan the license in store and it would prevent Terri from getting as many boxes as she did, unless she bought some herself as well. See more »

The One With The Mash-Ups...
14 June 2015 | by (Australia) – See all my reviews

I really enjoy this episode. I love the girls' mash-up and it's just a really fun episode.

In this episode, Will challenges the Glee Club to make a mash-up of two songs. Girls VS. Boys. Meanwhile, Will's wife, Terri, takes a job as the school nurse, even though she has no medical or nursing training, and gives Finn a "Vitamin D" tablet to wake him up and he's more energetic. The boys group does this and then the girls decide they need to have it in order to make it fair.

Songs sang: It's My Life / Confessions Mash-Up by the boys of the Glee Club. Halo / Walking On Sunshine by the girls of the Glee Club.

Best part of the episode: Halo / Walking On Sunshine.

Worst part of the episode: Terri.

Overall, I give this episode a 10 out of 10, which in my ratings book is: Freaking Ridonkulous.
