paddy and murphy on a flight from gatwick to dublin, pilot comes over the tannoy and says due to engine number one failing we will be 20 minutes late arriving at dublin, paddy and murphy took no notice, 10 minutes later captain says due to engine number 2 failing we will be 35 minutes late arriving at dublin, again paddy and murphy hear the captain, but ignores it, 10 minutes later captain comes on the tannoy again, and says, due to engine number 3 now failing we will be about a hour late landing at dublin, paddy turns to murphy and says, bloody hell mate, hope the fourth engine doesnt go, we will be up here all night!
