Mimi and Oona are sitting in a cottage in the middle of nowhere. They've been drinking for seven days straight and they finally run out of booze.
Mimi says to his mate "Hey, go and look in the tool shed and see if there's anything to drink there."
Oona comes back with a bottle of methanol, and says "We could drink this, but we'll go blind!"
Mimi slowly looks around the cottage and out the window, and says "I think we've seen enough"
