From the tone of your submission you could just use your ego is sufficiently
that you really don't need backup.  I doubt very much if anyone gives a
sweet rat's ass whether or not you're a dealer OEM or Santa Claus.  If
you've got so much money maybe you send a few $$ to the Red Cross in NYC to
help out the poor bastards down there.

If I were you I'd go out and get a big bottle of humble pills and start
taking them religiously; you really do need to cure your problem before it
spreads.
