just saw a new soap commercial, Lever 2000, i think? anyway, the whole ad was a series of curious fingers exploring the skin of a group of different people. So, it was only a matter of time before, well... anyway, there is one girl, looked like late teens maybe(?), blond. well, one pair of fingers go for a stroll across the side of the girl's bare foot. there is then a closeup on her face, and she is clearly giggling. there is a voiceover throughout the commercial, with no other sound except for music, so you cannot hear the girl's reaction. it is very brief, but nice enough to mention.
