With apologies to John Landis for ripping him off for this one...
There was this aero plane over the Atlantic on its way to New York, and it was full of men from the United Nations. So halfway over the ocean the engines run low on petrol. So they have to lighten the plane. So they heave out all the baggage, but it's still too heavy. So they chuck out all the seats, but it's still too heavy. Finally, this Frenchman, he steps up, shouts 'Vive la France', and leaps out. Then an Englishman, he steps up, shouts 'God save the Queen', and he leaps out. But the plane is still too heavy. So the Yank delegate, from Texas, he steps up, shouts: 'Remember the Alamo', and chucks out the Mexican!
