A couple more videos:
http://www.youtube.com/watch?v=dKtIi1OzUpo - Chelsea "sexually assaults" her staff. She's in her bra and pushing her boobs on a guy's head at the 1:00 mark.
http://www.youtube.com/watch?v=gQo5s1IVQEk - Prank from "Girls Behaving Badly" in which she adjusts her boobs and tries to get people's opinions on how her boobs look.
Enjoy
