A Mexican drinks his beer and suddenly throws his glass in the air, pulls out his pistol and shoots the glass to pieces. He says, "In Mexico our glasses so cheap we don't need to drink from the same glass twice."
An Iraqi, obviously impressed by this, drinks his beer, throws his glass into the air, pulls out his AK-47 and shoots the glass to pieces. He says, "In Iraq we have so much sand to make glasses that we don't need to drink out of the same glass twice either."
The REDNECK, cool as a cucumber, picks up his beer, drinks it, throws his glass into the air, pulls out his gun, shoots the Mexican and the Iraqi then catches his glass as it falls into his hand.
He says, "In America we have so many illegal aliens that we don't have to drink with the same ones twice."
