When Mike Shelby (George Wendt) walks into Hilda's Cafe, everyone in the place yells "Mike!" just like in Cheers, when his character Norm walked into the bar, and everyone yelled "Norm!"
The title is based upon the novel I, Claudius by English writer Robert Graves, first published in 1934, that deals sympathetically with the life of the Roman Emperor Claudius and was turned into a miniseries in 1976.
