While sticking some electrodes on an 85 year old patient's foot, I was trying to explain to him what I was doing....
Me: "So now I'm going to look at some of the nerves in your foot."
Patient: "My crotch?"
Me: "No, your foot."
Patient: "My butt?"
Me: "No, your foot." [taps his foot, now covered in sticky electrodes] "This thing."
Patient: "Oh. I don't hear very well."
