Ole & Sven
Ole and Sven are walking down a street in Minocqua WI, when they see a sign on a store that reads, Suits $5.00 each, shirts $2.00 each, and trousers $2.50 per pair.
Ole says to his pal, "Looky here! We could buy a whole gob of dese, take 'em back ta Dulute, sell 'em to our friends, n make a fortune. Now when we go in der, you be quiet, okay? Just let me do da talkin cuz if dey hear yur accent, dey might tink we're ignrant n try to cheat us. No way, dey'll know we're from Minnesota."
They go in and Ole says with his best Wisconsin accent,
"I'll take 50 of those suits at $5.00 each, 100 of those shirts at $2.00 each, and 50 pairs of trousers at $2.50 each. I'll back up my pickup and ...."
The owner of the shop interrupts, "You're from Minnesota, ain't you?"
"Vell...yeah," says a surprised Ole, "How'd ya know dat!?"
"Because this is a dry-cleaners......"
