When Mike is named Sexiest Man in New York by ""Manhattan"" magazine, he has difficulty living up to the notoriety at home. In the meantime, the staff must deal with Mayor Winston's problematic wife during an important dinner.

For the Mayor's 50th birthday, Paul is determined to get his ""old friend"" George Stephanopoulos to attend the event; as Michael arranges for birthday wishes from David Letterman, Patrick Ewing, Al Michaels, Dan Dierdorf, Frank Gifford, Rosie O'Donnell, Larry King, and the cast of Rent. But in the midst of the planning, a scandal swirls about the Mayor's presumed affair with a staffer from the Governor's office.

The Mayor separates from his wife and moves in with Michael, much to Mike's chagrin. Meanwhile, designer Isaac Mizrahi helps the Mayor's office with a charity fashion show and gives Nikki a once-in-a-lifetime chance to strut the runway in one of his creations.

The Mayor is disturbed by a campaign commercial by his opponent, starring his ex-wife. Mike plans the City Hall Thanksgiving, scheduled to be televised live throughout New York City, with the Mayor's father scheduled to attend. At the dinner, the Mayor blows up at his father on live TV. Meanwhile, Stacy mistakes Stuart for her boyfriend in the dark and lays a big wet one on him, making her think twice about her feelings for him.
