There are a number of quotations by Winston Churchill which, for some reason unknown to me, all concern his fly being open. Did the man walk around permanently unbuttoned in those PZ (pre-zipper) days inviting comment?
On being told by an MP that his fly was open:
"It is of no account, after all, dead birds do not fall from their nests."
When told by a man in the street that his fly was half open he said
"or perhaps it it is half closed"
then continued walking down the street.
Once, when Churchill was sleeping on a train, a woman came in and noticed his fly was open. She said "Mr, your penis is sticking out!".
Churchill awoke, and answered:
"Madam, don't flatter yourself. It is merely hanging out."
