David Martinez, Spanish teacher
Language Arts: "One day I realized I was spending so much time flossing that I was missing my life. I want to make a difference that lasts longer than a grin."
Attendance: Season 2, 1 episode: "The Spanish Teacher"
Glee Club Cred: A ridiculous half-Spanish version of LMFAO's "I'm Sexy and I Know It," and an awesome duet of Madonna's "La Isla Bonita" with Santana.
Grade: A-: Martin was the bright spot in an otherwise ridiculous episode. And since he's now McKinley's new Spanish teacher, we'll likely see him again. The only downside: we're dismayed the Latin heartthrob had just two tunes in his "Glee" debut.
