Nothing

Do nothing. Absolutely nothing. Get up to go to the bathroom only if in dire need. Need food? Get some delivered. Can't be bothered to get dressed to meet the delivery guy? Stay in your underwear and eat that ramen you've been saving in the cupboard in case of an emergency. There isn't anything better than laying in bed all day watching cable tv. Well, there is one thing and that is to watch tv for a short while and then roll over and go back to sleep. Repeat as necessary.
