First they done a lecture on temperance; but they didn’t make enough for them both to get drunk on. Then in another village they started a dancing-school; but they didn’t know no more how to dance than a kangaroo does…They tackled missionarying, and mesmerizing, and doctoring, and telling fortunes, and a little of everything; but they couldn’t seem to have no luck.

– Mark Twain
