I enjoy teaching woodworking. I have to thank my father for cluing me in at an early age what tools were used for what tasks. Where I teach we get groups of scouts coming in to make their Pinewood Derby cars. It is always obvious which fathers are competant in a shop and which are actually bad influences on their sons. Sometimes the fathers get way too involved in the design of a car but have no idea how to execute that design. More often than not the fathers will split into two groups. One group will work with the boys sincerely trying to create a car that will not be an embarrassment to the kid on race day. The other group of fathers will abandon their sons and gather in a corner of the shop to discuss investment strategies, the new Bimmer or how hot the nanny is.
The latter group would know the difference between a hack saw and a table saw and their kid never sees them but they consider themselves superior to me as I teach their sons shop safety. Here is a video made by (what I am guessing is) one of their kids:
