Tickled by a Beastie Boy?

In this clip from the "Licensed To Ill" tour, a very young Ad-Rock decides to autograph a girl's breast backstage. But when the pen gets too close to her armpit, she reacts and squirms away, shyly, almost as if to say "hey, that tickles". Later in the clip, Ad Rock dances with her and picks her up; when his hand reaches her hip bone, she squeals and giggles. (she's already delighting in the antics, but the shriek of giggles occurs when his hand wanders to her hip). Inconclusive but kinda hot.....reminds me of.....me! lol.
