Another couple of favorites in our house, both from "Negative
Reaction"....
(1) It is cold outside and some is looking for their
coat, someone invariably says "that coat...that coat" (line from nun played by Joyce Van Patten).
(2) Someone asks someone else if they are eating some particular food...the answer is "that is the prevailing theory!"-quote by Mr Dolan played by Vito Scotti.
