I´ll buy one, take it to every metal festival and put the speed to maximum for maximum headbang robot
and during the night I´ll keep her in an extra tent and sell her out to drunk dudes to retrieve the costs for both the puppet and the extra tent
I´ll call it the "Full Metal Wandering Whore" and it´ll be a legacy
I´d bring my enemies to the tent, just to activate a secret overcharge mode I installed previously and I´d laugh as the machine will rip of their dongs, flailing the bloody end around like a dead fish, spraying dickblood, piss and semen onto the insides of the tent. The fool would be bawling in pain and agony while I´d be outside, laughting and choking on my beer, knowing that there´s a secret videocamera inside of the tent, witnessing the metal-whores demonic dickfeast. I´d sell all copies of the video to my only, but faithful customer, Xant but keep one copy for myself to watch every year on christmas eve with hot cocoa and eventually, eggnog.
What would you do with such a machine? Tell me your plans for world domination
