And when it's over, the clueless Mr. Schue inquires as to the nature of the children's unusual footwear. Frankenteen explains that they got the idea to wear "Mexican hipster boots" from Ricky Martin, which allows Santana to stab at Mr. Schue's fragile sense of professional self-esteem like so: "The teeth, the duende, the bizarre Mexican fads -- Señor Martinez is, like, the best Spanish teacher ever!"

"I'm sure you have something muy amazing planned!" She's such a bitch. And I love her so much for it.

Excellent.
