In honor of the above Mark Twain quotes, here's a Mark Twain anecdote.
While giving a speech on honesty, Mark Twain told this story:
When I was a boy, I was walking along a street and happened to spy a cart full of watermelons. I was fond of watermelons, so I sneaked quietly up to the cart and snitched one. Then I ran into a nearby alley and sank my teeth into the melon. No sooner had I done so, however, than a strange feeling came over me. Without a moment's hesitation, I made my decision. I walked back to the cart, replaced the melon -- and took a ripe one.
