Weirdest Compliment Ever

I was giving one of my subjects a 12-lead EKG, which involved her lying topless on an exam table while I counted down her ribs to the intercostal spaces where I place the electrodes.

Subject: You would make a really good doctor.
Me: (flattered) Thank you! Maybe someday...it takes a lot of schooling.
Subject: (pause)
Subject: ...Oh, no, I meant like a street doctor. You'd be real good at sticking people right in the clavicle.
