How can someone accidentally shave their head?

This was probably the dumbest thing I've done in a long time!

Just before we left for our 2 week trip to PA to see our family, we were busy getting ready to go. Renee asked me to cut Callan's hair before we left. Since he has become afraid of the trimmers, I have to cut his hair with only scissors while he watches Yoshi videos on youtube. So as I was finishing up his hair and getting ready to do mine, Renee said that she had scheduled a shotgun doctor's visit before our trip since our kids had been sick.

She gave me a 10 minute warning and listed off a few things to try to get done if I could before she got home. My mind was thinking about that to-do list while I was cleaning out the trimmers and I went to cut my hair quickly. Without thinking I took it through my hair and... wah lah


At this point I only had two options.

1) Mohawk (but I am 32)

2) Shave the rest of my head

This picture was actually taken 4 or 5 days after the initial shaving, but you get the point.
