my printer was connected to my laptop and i tripped over the wire and it yanked out the little ledge in the usb port rendering the port useless and cracking the plastic around it, thankfully i have 3 others on my computer so it's not so bad!
The worst mess i've ever made in my house was when i let my daughter do her abstract paintings in the living room, so now there's paint all over the walls, hahaha! i don't think it's going to come off.
