C: Crystal Club Cola The soft drink that you see Dunder-Mifflin employees occasionally sip in the employee lunchroom is a real regional soda brand from eastern Pennsylvania. D: Diversity Day The hilarious episode about sensitivity training was partly inspired by a sexual-harassment seminar the cast and production staff was required to go through once NBC hired them for the show. E: Edgar Steve Carell has played unctuous and annoying before as Edgar, Ellie's ex-boyfriend on Julia Louis-Dreyfus' short-lived sitcom Watching Ellie. F: "Fundle Bundle" The clip of this fictional Scranton kiddie TV show with little Michael Scott gave us an early glimpse of his lonely misfit side. G: Grass Roots Remember the 1960s hit "Midnight Confessions" by the Grass Roots? Cast member Creed Bratton played guitar in that band. H: Halloween Only Michael would wear a Halloween costume with a papier-mâché likeness of himself on his shoulder on the same day he attempted to terminate an employee. I: "Islands in the Stream" One of the most annoying songs of the '80s made a great karaoke moment for Jim and Michael. J: Jay Ferguson The composer of The Office theme, Ferguson was lead singer in the rock bands Spirit and Jo Jo Gunne, and had a solo Top 40 hit in 1977 with "Thunder Island." K: Kiss The big cliff-hanger moment in Season 2's finale was when Jim finally planted one on Pam, even though she was engaged to shipping-department lug Roy (David Denman).

Novak (Ryan Howard) is a coproducer and Mindy Kaling (Kelly Kapoor) is story editor. U: Urine Dwight provided some to Michael to help him pass a drug test. But his guilt over it forced him to resign as a Lackawanna sheriff's deputy - a tragic loss for the law enforcement community. V: Valentine's Day Dwight got his own personal bobblehead. Angela (Angela Kinsey) got his key. Michael got a big kiss from Jan. Phyllis got flowers and a giant bear from Bob Vance of Vance Refrigeration. And Pam got a promise from Roy that she would get the best sex of her life. Uh-oh.
