I encourage people to sell shit on Craigslist to really get a sense of how well the American education system is functioning. I posted a double/queen bed frame, and a Tyrone (I shit you not) writes to ask if it fits a king sized bed. I post a desk, and someone emails to ask "What do the legs of the table do?" I write back: "They hold the top up so it doesn't fall down, you dumb cunt".
