Through the latter half of the 19th century, Mark Twain was on a mission to attack pretense with satire.

Nick C. asks: How did they settle on six feet deep for graves? If there’s one thing everyone knows about graves other than the fact that they’re really spooky at night, it’s that they’re always six feet deep.

When I was a kid, my parents had a collection of historic old, yellowed newspapers. For example, I distinctly remember an old Washington Post newspaper sitting on a bookshelf from July 21, 1969 with the headline “The Eagle Has Landed – Two Men Walk on the Moon.” Or a fading, brownish-yellow one from August 8, 1974 with the big headline, “Nixon […]
