glee john stamos matthew morrison 320 'Glee': John Stamos first lookOpen wide, Mr. Schue.

Here’s a peek at “Glee” guest star John Stamos, who as we know already, plays Dr. Carl Howell, a dentist love interest for Emma (Jayma Mays) in the second episode back, the Britney Spears episode.

In an interview with TV Guide, Stamos reveals that besides a degree in dentistry and a killer smile, Carl also has a secret weapon when it comes to wooing Emma.

“Just when Will thinks he’ll win Emma because he can sing and dance, we find out Carl used to be in an ’80s boy band,” says Stamos, who also worked with some of the other McKinley High students including Heather Morris, who plays Brittany.

The former “Full House” star will come back for the Halloween/”Rocky Horror Picture Show” episode.

“I can’t tell you what character I’m playing, but I will be singing,” he says.
