Late one night from the Norway Int'l airport, Sven and Ole phoned their wives back in the States to inform them of their expected time of arrival back home after their Scandinavian vacation.
Sven and Ole then boarded the 4-prop airplane headed back to the States. All was going well until the Captain announced over the PA system that there had been engine trouble in engine number 4, and as a result their arrival time in the States would be pushed back 30 minutes. Sven told Ole that this shouldn't be too much of a problem with his wife, as she was usually not punctual and would probably be late to get him anyway. Ole agreed, and the flight continued.
An hour later the Captain came on the PA system again, announcing that there had now been problems with engine number 1, and as a result the flight would be 60 minutes late in arrival in the States. This time it was Ole who spoke, telling Sven that now there could be a problem with his wife, as she was not an extremely patient person in these matters. Sven consoled Ole by telling him that he could ride home with him and his wife if Ole's wife didn't wait for the late arrival.
At about the same time the two had resolved the issue and drifted off to sleep, the Captain got on the PA system a third time. He announced his apologies, but there now had been troubles with engine 3, and as a result the flight would be 90 minutes late. It was at this time that Ole looked over at Sven, and in utter dismay announced, "For cryin' out loud. If another engine goes out we'll be up here all night!"
