Yep, one doctor did that to me with an electrode above my collar bone and one on my wrist. He let the one on my neck slip, and I got agitated. This was a small indian man (Dr. Lahiri, funny I have no problem remembering him), maybe 5'6" or so. I am a big fellow (6'5" and about 240 lbs at the time), and when he realized what he was doing was irritating me, you should've seen the big nervous grin that sprouted across his face. He was apologizing so fast I couldn't understand one word he said through his accent, but I knew what he was trying to say anyways, so I unclenched my fists and sat back down.
