On Dec. 21, Horton the Elephant and Gertrude McFuzz will take a break from looking for Whos long enough to share cocktails and conversation with Seth Rudetsky at his weekly New York City cabaret show, "Seth's Broadway Chatterbox." Actually, Kevin Chamberlin and Janine LaManna, the real-life actors behind the Seussical characters, will be on the receiving end of Rudetsky's questions, jokes and prompts.

Rudetsky, a comedian and writer for Rosie O'Donnell's TV show, hosts his variety show — the press materials call it a combination of "Mike Douglas, Dr. Seuss and Pee Wee Herman" — every Thursday at 6 PM at Don’t Tell Mama. There's a 2-drink minimum, but the $10 cover charge is donated to Broadway Cares/Equity Fights AIDS.

For information on "Seth's Broadway Chatterbox" at Don't Tell Mama, 343 West 46th Street, call (212) 757-0788. You can also check their website at : http://www.geocities.com/broadwaychatterbox.

Previous guests on "Chatterbox" have included Mary Testa, Andrea Martin, Faith Prince, Terrence Mann, Marin Mazzie, Kristin Chenoweth, Roger Bart, Bebe Neuwirth, Graciela Daniele, Bryan Batt, Barbara Walsh and Norm Lewis.

These days, host Rudetsky is also getting to shift the spotlight to himself, Saturday nights since Dec 2. His autobiographical one-man show, Rhapsody in Seth, plays at OOB’s HERE. Paul Castree directs this look at “childhood...growing up lauded for my musical talent and hated for being gay.” For tickets and information on the 11 PM show, every Saturday in December, call (212) 647-0202.
