The executive candidates on the NBC tour all share their first names with the five tour winners in Willy Wonka and the Chocolate Factory. In addition to this, they wear similar clothing and act in similar ways.
The title of this episode, "A Goon's Deed in a Weary World," is a reference to a line in the 1971 movie Willy Wonka & the Chocolate Factory: "so shines a good deed in a weary world." Wonka (Gene Wilder) delivers the line after Charlie returns an Everlasting Gobstopper to Wonka instead of delivering it to "Slugworth" and thereby passes Wonka's test, proving his integrity and inheriting the chocolate factory. The line in Willy Wonka & the Chocolate Factory was itself a paraphrase of a line from William Shakespeare's play The Merchant of Venice: "That light we see is burning in my hall. / How far that little candle throws his beams! / So shines a good deed in a naughty world." The word "goon" was an epithet that was often applied to the character of Kenneth throughout the run of 30 Rock, either alone or in combination with other insults--for example, "Apple-faced goon," "Albino goon," "innocent goon," and so on.
