Here's a very old musicians' joke (Events at Stormont have outdated this:)

Maggie Thatcher, Ian Paisley and Daniel O'Donnell were riding in a train through Ulster. Suddenly, the IRA raids the train.

The second-in-command asks: "Sir, we have captured Thatcher, Paisley and O'Donnell - but we only have two bullets. What shall we do?"

"OK," says the commander. "Leave it to me."

So they shot Daniel O'Donnell twice - just to make sure...
