Does anyone love puns with the passion that I do?

A steam train is crossing Poland at night, and is almost out of coal. The engineer tells the brakeman that the porter will have to go out to buy coal at the next stop, and to let him know what the next stop is, to ensure it has coal.

At the next stop (2:00 a.m.) the brakeman peers out at the sign and says "It looks like Danzig in the dark."

"Buy coal, porter!" yells the engineer.
