Things I've taught Malachi that are showing up recently:

wiping his most (snot) on his shirt sleeve. It makes my mother scream (like she did at me) and makes me so PROUD. my boy

bending over his plate to eat like a dog. I was only doing it to be silly then he started hahaha. this one might get me in trouble

I'll add more to the list, I'm sure. standby, you guys
