Two guys are in a doctor's waiting room. The first guy asks, "Why're you here?" The second guy says, "Endoscopy. He's going down my throat with a camera. Why're you here?"

The first guy replies, "Camera up the ass." The second guy remarks, "Oh, a colonoscopy?"

The first guy tells him, "Nah. My old lady caught me taking pictures of the neighbor's wife sunbathing naked."
