That's a really good question....
This Marine Fighter pilot retires after Viet Nam, and spends the next 30+ years leading a successful life when 911 occurrs. Goes to the local recruiter and tells him he wants back in. Says gonna kill rag heads Semper Fi, Do or Die oorah.
The Gunny tells him he's too old. The former pilot says no sweat, got a buddy at the pentagon, oorah. Calls his buddy at the pentagon and once again is told he is simply to old. No sweat, buy a boat gonna kill rag heads Semper Fi Do or Die Oorah.
So he buys a boat and is rowing it across the big water when St Peter sees him and points him out to God and asks "what am I to do about him?". God says take his brain and he'll turn around not remembering where he is headed. St Peter takes his brain, but still the Marine is rowing singing gonna kill rag heads Semper Fi Do or Die Oorah.
St. Peter once again points him out to God and says "now what", to which God says take his heart, it is from there his passion flows. So St. Pete removes his heart. The Marine is still rowing and singing gonna kill rag heads Semper Fi, Do or Die OORAH !!!!
Now St. Pete says to God, I really don't know what to do now, and God says take his balls, that removes his aggression, and St Pete does that. The marine turns his boat around and sings "Anchors away my boys".....
