This man walks into a gun shop and asks to buy a gun. The gun shop owner asks, "What for?" He says, "To shoot some cans." So he walks away with the gun.
He comes back the next day and asks for a bigger gun claiming he still has more cans to shoot. He walks away with the bigger gun.
Again he comes back the next day demanding a bigger gun. Now the gun shop owner is curious and asks, "What cans are you shooting sir?" He replies, "AmeriCANS, JaimaCANS, AfriCANS..."
