In real life, my washing machine likes to destroy my clothes if I don't put literally everything in lingerie bags.
So what about a washing machine that turns things semi-sentient, and homicidal? You wash your pants in the machine, dry them, everything seems fine.
Then you try to put them on, and they try to eat you. Shirts start to act like straightjackets, socks eat your feet, and the less said about panties and boxers the better.
Good idea? Bad idea? Stupid-ass idea?
