Two Irishmen were sitting in a four engined plane flying back from a shopping trip to Paris when the captains voice came over the loudspeaker. "Ladies and Gentlemen, one of the engines appears to have failed. There's nothing to worry about but we will be 15 minutes late in landing at Gatwick."
Five minutes later he said, "Nothing to worry about, ladies and Gentlemen, but one of the other engines has failed, and we will now be an hour late."
A moment later, "Er...sorry about this ladies and gentlemen, but the third engine has also given up the ghost and we will now be two hours later than expected."
One of the Irishmen tapped his friend on the shoulder. "Good heavens, Patrick, do you realise that if the other engine fails, we'll be here all night?"
