AAH Pythagoras!

All right. The latest phenomenon would be the recurring Pythagorean Theorem of perfection made by my brother Sam's lips. It's just miraculous. How can one little boy's human, normal mouth suddenly turn into a triangle? Literally. His mouth goes from:

mmm

mmmmMmmmm
mmmmmmm

to:

M
MmM
MmmmM

MmmmmmM
MmmmmmmmM

I just don't get it. Also, he takes pride in it. He calls it The Prehensile Lip because it's quite usefull for grasping onto who the hell knows what in his little boy world. Go Sam. Noah can't do it, which is even weirder. Identicle twins, yet Sam has somehow altered his face to be some kind of flubber, super versatile, stringy, flexible thing that's capable of turning out shapes never thought possible to exist in nature.

Obviously, we were wrong. Pythagoras rules.

a^2+b^2=c^2

I'll spare you and skip the proof.
