sit around and stare at the walls for 1/2 an hour, walk around the block, try to watch the tube and find out that only oprah and perry mason are on, stare at the walls some more, go to the kitchen and empty all the nitrous out of the numerous partially full whipped cream cans in the fridge, stare at the walls a little more, then fall asleep and wake up 2 hours after i was supposed to be at the appointment.
but i really wouldn't recommend it.
