Care to guess what’s behind door #1?

Before clicking through, try and take a guess as to what may be hidden at the bottom of that secret door (conveniently disguised as a collection of rocks).
Now why can’t this ingenuity go into something a little more productive?

Sweet! If only my next house was to come with a lair like that premade! i would make it into a gun range though oh and a small world domination satellite room.
Thats insane O_O I wonder how noone caught them building it though. Wouldn’t someone had noticed their neighbors building a giant underground tunnel?
Looks like a brand new house – Maybe they had some friends in the building trade and paid them off the record and with the less legitimate ‘green stuff’!
I’m in! I finally joined the gravatar crew. does that make me cool now?
Jeez, did they even have the brains to have an external motor? That shit probably sucked tens of thousands of watts…
