Read it twice

A bus stops and 2 men get out. They sit down and engage in an animated conversation.

The lady sitting next to them ignores them at first. But her attention is galvanized when she hears one of them 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."

The lady can't take this any more.

"You foul-mouthed sex obsessed pig", she reported indignantly, "In this country, we don't speak aloud in public places about our sex lives!"

"Hey, coola down lady," said the man, "Who talkin' abouta sex? I'm justa tellin my frienda how to spell 'Mississippi'. "

(I bet you're gonna read this joke again!)
