What Is That Smell?

Today I had a minor surgical procedure done. I had a mucus cyst removed - sounds pretty gross, but it was basically a little pocket of on the lining of my mouth.

The doctor sprayed my mouth with nasty-tasting topical anesthetic - it was like somebody described what a banana tastes like and someone with tanks of chemicals tried to reproduce the flavor - and then spent about five seconds getting rid of the cyst.

Then he grabbed a weird looking pointy thing and stuck it in my mouth. I felt a tingling like a mild electric shock, and noticed smoke wafting out of my mouth.

"What is that smell?" I managed to ask during a break in the action to get more gauze. The nurse replied "Your skin."

It smelled like burning hair. Funny, I always figured burning people would smell more like cooked meat.
