Every time the U.S. Cavalry major rode through
the camp of the recently subjected Indian tribe,
he'd deliberately wave to the old chief. And the
latter would reply by giving him the finger, in
the usual vertical manner, and then turning his
hand so that the same digit stuck out
horizontally.

After a few weeks of this, the major's curiosity
got the better of him; so he rode over after one
such exchange and said, "Look, Chief, I know what
it means when you give me the finger straight up,
but what the hell does it mean when you also give
it to me sideways?"

"It means," grunted the chief, "that I don't like your horse, either!"
