2 Italian immigrants get on a bus

A woman is sitting on a bus, and 2 Italian immigrants come sit down in front of her, she overhears one speaking to the other:

"Fredo, Emma come-a first,
Then-a I come-a,
Then-a the two asses they come-a together,
Then-a I come-a again,
Then-a the two asses, they come-a together again,
Then-a I come-a,
Then-a I pee 2 times,
Then-a I come-a one last time."

Offended she gets up and scolds the two men "You foul mouthed abhorrent men, in this country we do not speak of such things in public!"

One of the men turn to her and say "What? I'm-a just-a tellin my friend-a how to-a spell-a Mississippi!"
