Comedian Bob Newhart uses to tell only one side of a conversation in his routines.
In his routine "Ledge Psychology", (https://www.youtube.com/watch?v=MwXaTy0PMPw , at 3:30 min) , in which a police officer tries to talk someone out of jumping from a ledge on a sky scraper in Chicago, at one time the police officer calls down to Sam, the hot dog man, and orders two hot dogs. The hot dog man asks an (untold) question, and the police officer answers "No, no, to go!", which seems to be the point of a joke.
Now I know the meaning of "to go", since it is used in my language as well, but I'd like to know how you could express its opposite, so that it becomes funny in that context?
