A teacher asks one of her students if he wants to hear a joke. He says sure. She says, 3 birds are sitting on a telephone wire, if i shoot one of them, how many are left? The student says, none. The gunshot would have scared the rest away. The teacher says, no thats incorrect but i like the way you think. The student asks, can i tell you a joke? The teacher says yes. The boy says, three women are eating popsicles. One's sucking it, one's biting it and one's licking it. How do you tell which ones married? The teacher says, i don't feel comfortable answering this.
