My new favorite blog is Futility Closet because they post clever and useless-but-to-me tidbits like this.
“Place a glass of wine upon a table, put a hat over it, and offer to lay a wager with any of the company that you will empty the glass without lifting the hat. When your proposition is accepted, desire the company not to touch the hat; and then get under the table, and commence making a sucking noise, smacking your lips at intervals, as though you were swallowing the wine with infinite satisfaction to yourself. After a minute or two, come from under the table, and address the person who took your wager with, ‘Now, sir.’ His curiosity being, of course, excited, he will lift up the hat, in order to see whether you have really performed what you promised; and the instant he does so, take up the glass, and after having swallowed its contents, say, ‘You have lost, sir, for you see I have drunk the wine without raising up the hat.'”
Samuel Williams, The Boy’s Treasury of Sports, Pastimes, and Recreations, 1847
