Cheers

Jay Thomas, who played Carla's ice skating husband, Eddie, makes a surprise appearance. He's not on stage but in the audience and heckles the group for the way he was dumped from the show without an explanation.

Note Kirstie Alley holds back from laughing when John McLaughlin wishes them luck on episode 400. A half-laugh does escape her lips.

Aside from clips, Woody Harrelson is the only cast member to appear in character as Woody Boyd in the intro of this episode.

Shelley Long sits next to Roger Rees, who sits next to Rhea Perlman and the rest of the cast.

The end of the special features an extended, rerecorded version of Gary Portnoy's "Where Everybody Knows Your Name" that reinstates the song's original lyrics.

There is an extension to the opening credits and the title song. Before getting to the actor/actress credits, there are a couple of extra photos in the old-fashioned format.
