2 hours after having mine out I was helping a friend car shop. I was bending over to show this sleeze bag salesman that the car had been hit and repaired poorly, when blood came pouring out of my mouth. I had cooling peel and stick strips on the side of my face that looked like giant band-aids, so I'm sure it was memorable for him.
The pain didn't bother me so much as the taste of blood, especially the dried blood after sleeping overnight.
