Never seen these before, what's up with this kid? is he just epically delusional or does he have some mental illness? (serious question)
Well... some claim he is mental case but I disagree; dude drives a car, benches 315, load leg press full of plates for reps... you just don't do these things when you are retarded...
Delusional he somewhat must be - he has called himself "semi-pro bodybuilder"

Watch this video. It's very recent, only one day old. It reveals a lot of his life - it's part of his "my story" series.
In this video Jason also answers to people calling him "slow"!!!
He says he isn't slow - I agree. He is delusional and little over eager but that's hardly retarded or "slow"...
