That source deserves a little explanation.
“Godfrey Daniels!” is the euphemistic expletive (a 'polite curse') favored by W. C. Fields

This source mentioned is a book:
Godfrey Daniels! : verbal and visual gems from the short films of W. C. Fields
edited by Richard J. Anobile ; introducted by Raymond Rohauer.
New York : Darien House, c1975.
So now I'm wondering. That seems to imply the line is from one of his "short films," and if that is so, I wonder which one it is.
