Yeah, that was a great scene! It wasn't short like most mainstream scenes, he tickled her sides for what was probably a good 10 seconds, and she was laughing pretty hard. I didn't tape it, so hopefully someone will post the clip soon!
Just to clarify...it was great that there was tickling at all, and Pam is very cute, BUT--you cannot see Pam's face at all and only a small portion of her body can be seen as the tickling gets her laughing.
