Two men doing animated conversation

 The lady sitting behind them ignores them at first, but her attention is galvanized when she hears one of the men say the following:

“Emma come first. Den I come. Den two asses come together.

I come once-a-more. Two asses, they come together again.

I come again and pee twice. Then I come one lasta time.”

“You foul-mouthed swine,” retorted the lady indignantly.

“In this country we don’t talk about our s*x lives in public!”

“Hey, coola down lady,” said the man. “Who talkin’ abouta sexa? I’m a justa tellin’ my frienda how to spella ‘Mississippi’.”
