Hmm...

According to this Kid's Height Predictor...

if Chris (height 6'4") and I (height 5'7") were to have a son who was somehow 5'6" and weighing 120 lbs by age 10, his estimated adult height would be 6'9" -- MAN! That's a lot of stretchmarks! Not that the situation is even probable... but I was just curious about how realistic that script really was. :P
