Sounds kind of like this one
We should not make fun of the Mexican Airborne after their daring assaults on Eban Emal, and Crete, oh wait, that was the Germans.
Well there were their jumps into Normandy and Holland, Oh, wait, that was us.
Well, there were the jumps into Stanleyville and Kolwezi, Oh crap, that was the Belgians and French.
Have the Mexicans ever fought any one other than us and each other ?
