Seinfeld

Four single friends -- comic Jerry Seinfeld, bungling George Costanza, frustrated working gal Elaine Benes and eccentric neighbor Cosmo Kramer -- deal with the absurdities of everyday life in New York City.

The Office

This U.S. adaptation -- set at a paper company based in Scranton, Pa. -- has a similar documentary style to that of the Ricky Gervais-led British original. It features the Dunder-Mifflin staff, which includes characters based on roles in the British show -- and, quite possibly, people with whom you work in your office. There's Jim, the likable employee who's a bit of an every man. Jim has a thing for receptionist-turned-sales-rep Pam -- because office romances are always a good idea! There's also Dwight, the co-worker who is successful but devoid of social skills and common sense.

Everybody Loves Raymond

Ray Barone is a successful sports writer and family man who deals with a brother and parents -- who happen to live across the street. Mom Marie loves to meddle in his life, while older brother Robert sometimes resents his success, and Dad Frank just makes comments and raids the fridge. Nevertheless, Ray manages to keep a bright outlook and a sense of humor, leaving the hard issues to his more-practical wife, Debra.
