Mississippi

A bus stops and two Asian men get on. They seat themselves, and engage
in animated conversation. The lady sitting behind them ignores their
conversation at first, but she listens in horror as one of the men says
the following:

"Emma come first. Den I come. Two asses, dey come together. I come
again. Two asses, dey come together again. I come again and pee twice.
Then I come once-a more."

"You foul-mouthed swine," retorted the lady indignantly. "In this
country we don't talk about our sex lives in public!"

"Hey, cool down lady," said the man. "I'm just telling my friend how to
spell Mississippi."
