Tom Pelphrey has been back on Guiding Light as Jonathan for just a week. But, as the actor tells Soap Opera Digest, he's already back to a few of his old bad habits.

In a few days, the character has nearly knocked someone over the head, drugged an unsuspecting victim and run off with Sarah again.

"I love it," said Pelphrey. "We have so much fun with everything."

The actor is thrilled to be back on Guiding Light, but admits that returning as a character everyone thought was dead proved to be a somewhat awkward transition.

"Things have to happen really fast," he said. "Soon after I get back, they have [the story] pick up, like, 'Oh, my God! You're alive?' We had these scenes with Ricky Paull Goldin (Gus), and he'd say, 'Are we going to address the fact that I thought you were dead?' and [the-powers-that-be said] no, so Ricky would come in and do a double-take and start talking. It's been kind of funny."

The laughs don't stop there on set.

According to Pelphrey, Daniel Cosgrove has been responsible for tons of side-splitting since he returned to Guiding Light.

"Every day I work with Danny there's a hilarious outtake," said Pelphrey. "The other day we were doing a scene and we were supposed to be angry at each other, so we were straight-faced. All of a sudden, Danny pulls a huge roll of duct tape out of the inside of his jacket and he says, 'Shut the door so we can get real.'"
