I thought the Churchill one was:
"But in the morning Madam, I'll be sober."

(So the "You'll still be ugly" was implicit rather than explicit.)

re "One small head" here is a fuller quote:

The village all declared how much he knew;
Twas certain he could write, and cipher too;
Lands he could measure, terms and tides presage,
And even the story ran that he could gauge.
In arguing, too, the parson own'd his skill,
For even though vanquish'd, he could argue still;
While words of learned length and thundering sound
Amazed the gazing rustics ranged around;
And still they gazed, and still the wonder grew,
That one small head could carry all he knew.
