Diane this is for you, up there in New Hampshire. The joke is taking place in Mississippi but then again I saw your quote of Emma Peel which reminded me of this. Usually I tell it close friends so they don't react like the old lady in the story.
that's how it goes.
A bus stops and two men get on. They sit down and engage in an animated conversation with a heavy italian accent.
The lady, distinctively looking from the south, notice their accent but ignores them at first, but her attention is galvanized when she catches this conversation:
Emma coma first, Then I come
Then two asses come together
I coma once-a-more
Then two asses, come togeder again
and I come again, and pee twice
Then I come one lasta' time.
"You foul mouthed swine" says the lady. "In this country we don't talk about our intimate lives in public!"
The poor fellas embarrassed, realizing what the old lady may have understood and the story teller to reply:
"hey coola down lady, I'm justa tellin' my cousin how to spella Mississippi".
lol!
