I didn't laugh either.(Well the hairy car description made me chuckle.) I'm still trying to figure out why it bugs him that people put their kids drawings up. Why not go the whole hog and complain about people putting up photos of their ugly partners and kids, and really be offensive?
As well, he was right off on his marking system. If you look at all those pictures they show that the kids have all really well developed skills -using size, proportion, body detail, shapes. In fact, those kids are really clever artists. Even the hairy car shows the child is experimenting with drawing wind, speed and direction - very clever.
Oh, and just to be completely pedantic, it's "than" not "then." I hope that was Echani's mistake not Maddox's(?) It would sort of undo his whole "I am the best" thing if he couldn't spell.
