A boat captain and his crew are sailing down a river to bring reinforcements to the battle of the Alamo.
The captain stands up about halfway through the trip.
"Gentlemen, our ship is too heavy. If three men do not jump overboard, we will all drown."
There's silence for a few moments, and then an Irishman stands up.
"Ach, remember me lads!" he proclaims, then jumps overboard.
Inspired by this moving performance, a Brit stands up and says "Remember me, guvs," then jumps overboard.
Nothing happens for several seconds, till finally, a Texan stands up.
"Remember the Alamo," he says solemnly...
Then he throws a Mexican overboard.
