Hahaha!! This one cracks me up!!
If I didn't know better, I would say my son might have done this road work. I've watched him "vacuum" around large items that sit in the middle of the floor. You know, a piece of paper gets knocked off the coffee table, and rather than pick it up he vacuums around it.
So...I'm guessing the guy (oh yes I'm assuming it was a guy because NO WAY would a woman do this) who did this is either about 15 years old...or he's at the bar slowly killing off more brain cells as we speak.
