Parting words from Monty Bodkin to Lord Tilbury in the second chapter of Heavy Weather (1933) by P.G. Wodehouse:
“I have only two things to say to you, Lord Tilbury. One is that you have ruined a man’s life. The other is Pip-pip.”
This reminded me of the classic from Right Ho, Jeeves:
“Very good,” I said coldly. “In that case, tinkerty tonk.” And I meant it to sting.
