|This drunk gets on a bus and asks the driver how long the trip is between Limerick and Cork.|
About two hours," says the conductor.
"OK," says the drunk "then how long is the trip between Cork and Limerick?"
The irate driver says to the drunk "It`s still about two hours. Why`d you think there`d be a difference?"
"Well," says the drunk, "It`s only a week between Christmas and New Year, but it`s a long time between New Year and Christmas !"
