Who's the Boss?

indeed.

Tony Danza seems to be itching to teach in Philly.

The actor/producer and a team of producers are creating a reality show for A&E in which Danza revives his pre-show-biz career as a history teacher. Though the Hollywood trades have reported that the series will be set in his native New York - think Welcome Back, Kotter - Danza hints that a Philly school has been selected.

Danza was spotted Monday night at Alma De Cuba with Mayor Nutter and his wife, Lisa, and Greater Philadelphia Film Office head Sharon Pinkenson, all of whom declined to comment. Danza also met Tuesday with schools chief Arlene Ackerman, whose spokesman had no info.

Danza himself, though, is talking. In a video clip on his Web site, www.dailydanza.com, he says he toured Philly schools, and playfully suggests that he has to become a Phillies fan. An A&E rep said nothing has been confirmed.

Pantoliano, in town to premiere his documentary about mental illness (No Kidding, Me Too!) and to speak at Friends Hospital, was followed discreetly by a building worker wielding a scooper.
