Am I the only one who finds intense pain to be humorous?

After starting the project of replacing a deck on my house three months ago, I have finally finished.

I was four nails away from being done. It was getting dark outside, and I was tired.

Long story short--I smashed my thumb with the hammer.

I knew immediately, that it was going to be bad, so I started inside.

I got a cup of ice water to put my thumb in.

The pain from this injury was ridiculous. It was so terrible, that I started to laugh at how bad it was.

Is this normal?

Does anyone else here ever laugh at how bad something hurts?
