Unless on goes all scatological and interprets ‘W.C.’ As ‘water closet’ - a euphemism for a bathroom, which may still be used in the US Navy.

We, the viewers have been with Fields since he left the house for an errand, and we have seen Fields through an improbable sequence of events.
As he returns home, opens the door and enters, his complaining, domineering wife asks, 'where have you been?'

Fields replies, "Things happened!'

He was a comic genius. One of my all-time favorites.
