Quote from Sam in The Sam in the Gray Flannel Suit
Norm: Uh, we're running late for our next appointment anyway, boys. Sam: Where is that? Cliff: It's at the bottom of the lobby escalator watching the secretaries go up to the lunchroom. [guys chortling] Norm: All aboard for the Underalls Express, now leaving Track 29. [guys imitating train whistle] Sam: [laughs] You mugs!
