This boy is too observant.
Brooks looks over at Dean one day, while Dean was doing P90x, and said “dad, if you want to get really big muscles, you have to take your shirt off.”
So now, whenever he wants to exercise with daddy, he takes his shirt off. I guess Brooks realizes all the guys with really big muscles are usually shirt free showing off their six pack. And he’s right – you don’t see many obese guys dying to show off their bod with no shirt, just the ripped ones!
Five year old correlation.
