A blonde is on a four-engine plane crossing the Atlantic.
All of a sudden there's a loud bang. The pilot announces over the intercom, "I'm sorry, one of our engines has just shut off. We'll be delayed 45 minutes".
Suddenly there's another bang. Once again, the intercom clicks on and the pilot expresses his regret they'll be delayed two hours.
Shortly after, there is third bang and the pilot announces they'll be delayed three hours.
The blonde turns to the guy sitting beside her and says, "Man, if the fourth engine shuts off we'll be up here all day".
