A Frenchman, an Englishman, a Texan, and a Mexican are riding a plane... …when the plane's engines fail and it starts to go down.  The pilot grabs one of the parachutes and jumps from the plane.  The remaining passengers see that there is only one chute left, and quickly do the math.

The Englishman stands up, straightens his tie, says "God save the Queen!" and jumps from the plane.

The Frenchman, not wanting to be seen as less noble than the Englishman, says "Vive la France!" and jumps to his death.

The Texan stands up, straightens his cowboy hat, says "Remember the Alamo!" and throws the Mexican out.
