Holy crap! I want to buy this place, just to invite people over and pretend like everything is totally normal.
If anyone mentions clowns, I'll just play dumb.
Then start to do every increasingly more creepy/scary things, like cut a cake for dessert with a knife that's just a little too big for the job etc...
Then after they leave, relieved to finally be out of the creepy place, they'll start to hear warped calliope music coming from somewhere. Drive faster! It can't be in the car can it? (of course I attached a mp3 player pumping out the tune someplace inconspicuous while on a bathroom break).
Man, you could have so much fun with a place like this!
