This Irish joke section is kindly contributed by Chris and Walter from San Francisco (ie I will not be held responsible!):
Two Irishmen are flying home from London. Shortly after taking off there is a big explosion and the pilot announces that one of the four engines has gone and the flight will take 20 minutes longer. Not long afterwards the pilot announces that a second engine has failed and the flight time will be 40 minutes longer. Half an hour later the pilot speaks to the passenger again to say that the third engine has gone out and they will arrive an hour late. At this time, one of the Irishman turns to the other and remarks "I hope that fourth engine keeps going or we'll be up here all night."
