You're pumped up for the Britney Spears episode of Glee, right? (No? Well, just pretend you're pumped, okay?) Here's a reason to love the Britney episode: It's the first time we'll get to see John Stamos in his role as Emma's dentist boyfriend. That's right: Uncle Jesse's big debut is also Britney's!
Don't get too excited though: Stamos says he doesn't share any scenes with Britney, meaning we can effectively kill the rumor that Britney will play his dental hygienist. Of his profession on Glee, John says he doesn't have big enough hands to be a dentist. Uh, okay!
