Kelly Dwyer is picking up on the Gino phenomenon. He explains it to the world thusly:
This is fantastic, and I'm beyond frustrated that I didn't discover this months earlier: Boston's got a secret, they're not sharing it, and for that, they should be ashamed.
As far as I can gather, toward the end of Celtic home games, the TD Banknorth Garden plays an ancient American Bandstand clip on the Jumbotron with KC and the Sunshine Band's "Shake Your Booty" (or, pardon my brevity, "(Shake, Shake, Shake) Shake Your Booty") as the musical accompaniment. The clip is usual spliced with shots of Celtic fans shaking their respective booties along with the song. Toward the end of the AB video, however, there is a shot of a rather hirsute Gino Vanelli fan (with a requisite Gino Vanelli t-shirt), that causes C's fans to absolutely lose their Skittles.
And of course Marc Spears gets credit for pointing out where you can pick up a Gino shirt for yourself (or a loved one).
