I'll present an alternative scenario just for the hell of it
Take the money, buy a full rack of assault rifles. AR-15, Sig 552, SKS-47, a few H&K MP5s...
Buy an intercom system and a *very* strong front door. Somebody stops by very pissed off, wanting their money back (most likely drug dealers with guns), answer the door with your new toys and forcibly convince them that they have the wrong address.
If you live in Texas, shoot them, drag them into your house and call the police for breaking and entering.
Spend the rest of the money on whatever you want.
