LOL! Only problem is Art...I did a little study on Nature vs. Nurture when I was younger and used my brothers in the experiment. I pounded the crap outta my two younger ones for about 12-13 years.
Nurture won

They now stand a solid 5-7" taller and outweigh me by 75lbs on the average!
I believe that first one entirely though. I bought the first one at Cabela's and they went back a week later...whole new staff and I was from Mars when I asked if they'd get them again[:@]
