As with most in their younger days, building random things from lego blocks was always a favorite passtime. You would drag out the box, dump it on the floor and build whatever was on your mind from the last cartoon, movie, or television program you had seen. Sometimes you would have a friend over when they urge to build would strike. For some reason, these kids were always satisfied having those one or two random bricks in their creation that didn't match. Why does the grey space fighter have a single red brick on one side of the body? Once they left, smash and back in the box.
What does this have to do with your kitchen? Your house is fucked. Burn it down and start over.
