An Irishman, a Mexican and an American are in an Plane...

The Irishman throws a potato out of the plane,
"Why did you throw a potato out of the plane?" asks the Mexican and the American.
"Because there is far to many in my country," replies the Irishman.

The Mexican then throws a Taco out of the aeroplane.
"Why did you throw that taco out of the aeroplane?" The Irishman and the American ask.
"Because there are far too many in my country," the Mexican replies.

Then the American throws the Mexican out of the aeroplane.
"Oh my God! Why did you do that?" The Irishman asks.
To which the American replies.

"That was my taco."

edit: I realise that it is a plane, not an plane, forgot to proofread.
