Shooting Cans

A guy walks into a gun shop to buy a gun.

"Can I help you sir?" asked the shopkeeper.

Ah, yes... I want to buy a .44 Magnum please.

The shopkeeper informs the man that the .44 is a very powerful gun, and asks the customer what he's going to use it for.

The man replies, "I want to shoot cans!"

What? Cans! You don't need a .44 to shoot cans sir, a much smaller gun would do, advised the shopkeeper.

The customer has enough and finally says, "Shut up and give me the dang .44 Mag... I want to shoot AmeriCans, MexiCans, and AfriCans!
