Can confirm. I lived with one many years ago — once. Never again.  Tons o’ Fun regularly obliterated the kitchen, ate others’ food without asking, hid drinking glasses full of chewing tobacco spit in odd places where they weren’t discovered until months later, and once vomited right outside the house but couldn’t be arsed to clean it up, like any self-respecting human would. When confronted with these activities, he’d either reeee in protest or suddenly pretend that he couldn’t understand English. It was a joyous day in the household when Tons O’ Fun finally decided to roll on his merry way.
