Going Once, Or Twice?

A Mexican, an Iraqi, and a redneck girl are in the same bar. When the Mexican finishes his beer, he throws his glass in the air, pulls out his pistol, and shoots the glass to pieces. He says, "In Mexico our glasses are so cheap we don't need to drink with the same one twice." The 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 with the same one twice either." The redneck girl, cool as a cucumber, picks up her beer, downs it in one draft, throws the glass into the air, whips out her .45, and shoots the Mexican and the Iraqi. Catching her glass, setting it on the bar, and calling for a refill, she says, "In America we have so many illegal Mexicans and Arabs that we don't have to drink with the same ones twice."
