Pun In Poland

A steam locomotive passing through Poland one night was running low on coal. The engineer says to his fireman, “We’re coming to a town, let’s stop and send the porter out to get more coal. It’s pretty dark but can you see the name of the town on the depot sign?”

The fireman replies, “Ah…it appears to be Danzig in the dark.”

And the engineer shouts, “Buy coal, Porter!”
