Three men in prison are about to be executed. There are three men standing in a prison yard, about to be executed for their crimes. They are offered a choice in execution style; beheading via guillotine, death by firing squad or an injection of HIV. The first man chooses beheading. He's led to the guillotine by the guards, positioned, and executed. Blood sprays everywhere and his head goes rolling across the yard. Horrified by what he's just seen, the second man chooses to be shot. The guards lead him to a wall, six other guards point their weapons at him, and they open fire. The man dies fairly slowly, choking on his own blood. The third man is totally calm. He says, somewhat smugly, that he'd like to be given the HIV injection. The guards summon the doctor, who gives the third man his injection. Back in his own cell later, the third man begins laughing quietly to himself. Confused, his bunkmate asks what's so funny. ""Those idiots,"" the man replies. ""I was wearing a condom the whole time!""
