Who's the jerk now!

He's 12.
I realize certain changes are right around the corner. Changes in attitude, perception, voice, friends and many, many more. I was sitting watching football when an excited shout came from his bedroom. "I CAN JERK! I CAN JERK! DAD, I CAN JERK!"
I knew he would be excited about it. Announcing it to your father though? You just don't do that! Nobody wants to know!
He came out of his room with a huge smile on his face, wearing only boxers.
"Dad...check it out...I can jerk!"
"AAAAAGHH!" I spun away and quickly averted my eyes. Oh the horror. Has this kid no humility?
"Daaaaad...look!"
I could hear feet pounding on the ground so I peered through fingers. It was just a dance.
He proceeded dancing some sort of reverse running man. Head tucked to chest and mouth gaping open. Which means REAL CONCENTRATION is happening here people.

Thank God it was only a dance...for now.
