I had a film professor who claimed that Wilder's response to that was "Go shit in your hat!" No idea if it's true, but it makes a great story.

TBSR: Even if it's not true, I think we have to act as if it is. It's such a Wilder type thing to say. And like they said in the movie "The Man Who Shot Liberty Valance":

"When the legend becomes fact, print the legend."
