“Life seems but a quick succession of busy nothings.”
Dinner was soon followed by tea and coffee, a ten miles' drive home allowed no waste of hours; and from the time of their sitting down to table, it was a quick succession of busy nothings till the carriage came to the door, and Mrs. Norris, having fidgeted about, and obtained a few pheasants' eggs and a cream cheese from the housekeeper, and made abundance of civil speeches to Mrs. Rushworth, was ready to lead the way.

“There is nothing that will make an Englishman shit so quick as the sight of General Washington.”
Retort attributed to Allen, during his captivity among the British, commenting after a picture of Washington was hung in a outhouse, in an anecdote told by Abraham Lincoln, as quoted in Lincoln, Vol. 1 (1996) by David Herbert Donald; the documentation on this is scanty, and it conceivably arose as a comical anecdote as early as Lincoln's time.
Variants:
