I don’t know how to use a post hole digger. Like Jim Voorhies says, I’m too smart to do manual labor. No, seriously, look:

Using a post hole digger is, or should be, part of every child’s
education. (I say every child, but practically that means every male
child. Girls aren’t as stupid as boys and know better than to do manual
labor.) I say this for several reasons. First, most of us are descended
from some form of immigrant who probably came here poor and had to work
at manual labor to survive. Digging post holes we channel out inner
ancestors. My inner Irish immigrant Kane ancestor merged with my psyche
somewhere during the second hole. The other reason that all boys should
be taught how to use this device is so they will know how painful it is
to make your living through hard physical manual labor. If digging a 3′
deep hole doesn’t scare them right back into school, nothing will.

Don’t know how to use one? This Old House has got you covered with an instructional video right here.
