One of my old school friend's house where I used to hang out, his dad had like an entire Lego workshop. Guy would make all sorts of stuff and go to conventions. Look up "Great Ball Contraption" for some examples of the kinda stuff he'd work on.
Anyway, that dad was the only person I've ever met who insisted the correct plural of Lego was just "Lego," same as Pokemon or sheep or deer, or if you preferred, Lego bricks.
That's what this chapter reminded me of lol
