The hardest punch helicopter?

Question

What is the hardest punch you have been hit with and how did it make you feel? I was hit so hard that I heard a heliocopter inside my head and it was very loud and my finger nails turned cold. I was in a boxing match.

Answer 1

Took a hit and my bell was rung.  The ringing didn't stop until a day later.

Answer 2

The hardest punch I ever got made me want to throw up, but didn't.  But I was in lots of pain.  (groin X2)
