Who is every kid's favorite author? If you answered David Mamet, you are probably alone. Nonetheless, the hard-bitten and profanity-prone playwright does have a few tot-friendly pieces up his sleeve. Two of them are part of the Atlantic Theatre Company's "Mamet for Kids" series, which has been extended into late April.

The troupe has devoted is entire 1999-2000 season to Mamet, who co-founded the company.

The more familiar of the two plays is The Frog Prince, which was to have given its last performance March 27 at 7 PM, but has added a show on April 8 at 10:30 AM. The modern retelling of the Grimm fairy tale stars Brain Brooks, Melissa Collins, Casey Smith and Simon Suh. Todd Weeks directs.

The second half of the series is The Poet and the Rent, an unusual bit of physical comic writing from Mamet. In the piece, a poor young poet struggles to pay his rent and gets some jail time and a few pies in the face along the way. An eight-person cast is directed by Amanda Charlton. Remaining performances are March 27 at 9 PM, plus new shows on April 15 and 22, both at 10:30 AM.

The Atlantic has currently been offering American Buffalo, Mamet's seminal play about three small-time crooks. --By Robert Simonson
