The guy goes to the eye doctor. He's in the chair, and the docs checking his eyes left and right, grumbling to himself a bit. He says hold on a minute I need another piece of equiptment. walks out of the room, comes back with a different gizmo. Starts looking at his patient again, and says "Buddy, you're really going to have to stop masturbating". Patient says "Are my eyes really getting that bad?", doc says

"No, you're just freaking me out"
