Magic,
The scene I saw was either just before, or just after she and the guy did the "hibbedy-dibbedy," as the two are in that playful-on-the-bed mode. He is wearing boxers and is shirtless, and she is wearing red gym shorts and a white, sleeveless T-shirt (A "wife-beater shirt," a friend of mine calls them). He is painting her toenails with a magic marker, and she is giggling, while throwing her head back. He then starts to tickle her all out, and she kicks her feet and pulls them to her. Sadly, this whole segment only lasts about 10 seconds. Then she is shown only from the chest up, laughing in a way that indicates the tickling has moved to her belly area. The scene then ends. Total time, about 25 seconds. There is no insane, screaming laughter that we would all like to see, but it is girlish, bubbly, and NOT FAKED OR ACTED! Anyway, that's the way I saw it. Hope this helps, buddy.
Aloha,
Raul
