Tickling in "The Office"

[Raptor]

I was just watching an episode from the 1st season of the "The Office" called "The Hot Woman" which had a pretty cool tickle scene. Pam and Jim were talking when her boyfried Roy comes in to apologize for an argument they had. He asks her if she's still mad at him and puts is hands on her waist and procedes to tickle her while asking her if she is. Pam starts to protest for Roy to stop but starts laughing uncontrollably, squirming and saying she can't breathe. It seemed pretty believable so I wonder if "Roy" actually did tickle her for the scene. Lucky guy!
