Polish joke (just change the country to suit)
Two guys are standing side-by-side at a urinal.
One guy says to the other. "You're Polish, I see."
"I am, how did you know?"
"You were born in Warsaw General Hospital."
"That's right. Amazing."
"You were circumcised by Dr. Waszinski."
'That's amazing, how can you tell all that.'
"The poor old guy never could cut straight. You're peeing on my shoe."
