I've brought this thread over because most of us seem to be here now rather than there, and nobody did answer my questions.
The question was, what are some pairs of cities or regions that are about evenly matched and have friendly rivalry.
You offered
Edinburgh & Glasgow (kelda asked "Am I right in thinking you're an Ex-pat Scot? What with a name like Shuggy!?" No, but 7/8 of my ancestry is Scottish, and my maternal grandfather's first language was Gaelic.)
Philadelphia and Pittsburgh
Boston (Red Sox Nation) and New York City (the Yankees)
in Chicago, it's Cubs vs. White Sox....
Cleveland and Pittsburgh
Dallas and Ft. Worth
a football rivalry would be Philadelphia and Dallas.
(That's American football, y'all.)
New England Patriots and the New York Giants (another Boston/New York match up)
Omaha and Oklahoma City
Los Angeles and San Francisco.
--------------------
OK, here's the joke using one of the examples you offered.
On the front of the T-shirt:
Cleveland foreplay:
Y'awake, dear?
On the back:
Pittsburgh foreplay:
Did I wake ya, dear?
I would certainly offer versions with the names switched. Please let me know how you think this would go down, and if I should make any changes to suit local dialect or usage, eg "Ah" for "I" and "love" or (something else or nothing) for "dear".
(Incidentally, I think I first heard the first part with "Australia" and I invented the second part with a self-deprecating "New Zealand")
