You have to Laugh by Donners

What is the difference between ROG and a fisherman?
A fisherman sometimes catches things with his tackle.

Ba Boom - TISH.

Sorry, ROG. You know its the Munster way, though.
Here's another.

Take a scratch team, give them the shortest possible time to prepare, make them play weak provincial sides while you keep your best players on the sidelines, play your first test at sea level and your second on top of a mountain, and then celebrate like loons when you manage to beat them by a total of eight points.

Ba Boom....
That one looses a little in translation from the Afrikaans, I think.
