Boys club

The boys in our house have some sort of pact. I don't know what it is but whenever their is sorting, tools, anything that plugs in or has a motor they gather together like lemmings. Morty loves to hang with dad - literally! Whether its in the gym cleaning up, putting something together, rolling to stretch muscles or cleaning out his junk in the car or taking out the garbage - morty is at full attention. I can't figure out why any if these things would be slightly interesting?! Someone please explain it to me!
