LOL, this thread is hilarious.

Here is my equation....

Didn't puke during pregnancy but felt a little sick here and there
+ DS has a HUGE head
- DS has brown eyes
+ DS never slept much and barely napped as infant
- teeth came in at avg time
+ DS is tall and a big kid
+ drank lots of water
- didn't play classical music to my belly
x hadn't eaten red meat in 13 yrs and suddenly had cravings for it during pregnancy and ate a jr. whopper with cheese a couple times

= a PG kid

so there you have it. That's my recipe : )
