John Stamos’ ‘Glee’ Episode: Sneak Peek and Details! (VIDEO)

Is the world ready to see Uncle Jesse hang out with the Glee gang? Hopefully so, because John Stamos is set to guest-star on the runaway hit musical TV show on its much-anticipated Britney Spears episode (airing September 28).

The former Full House hunk will play dentist Dr. Carl Howell, who gives a check-up to Mr. Schuester (Matthew Morrison) and administers anesthesia to the rest of the cast, sparking a series of Britney-inspired dream sequences.

The 47-year-old actor appeared on Ryan Seacrest’s radio show this morning to discuss the guest spot, revealing an awkward encounter with Glee cast member Heather Morris while filming: 

“I’m in this dentist’s chair, and [Morris is] basically giving me a lapdance.”

So, how did Stamos, um, maintain his professionalism during the scene? The actor notes,

“You think of your grandmother.”

Thinking about his grandma, even while he’s at work. Aww, how sweet!
