What do you do when the dog has 2 heads?

Call the doctor.  My daughter had her wisdom teeth out yesterday and came home and some time later, mentioned that since the procedure she had been seeing double on one side and that it looked like Cosmo had 2 heads.  By the time the doctor called back, it had pretty much resolved, but all in all, despite watching Back to The Future II and III and Raiders of the Lost Ark and Indiana Jones and the last Crusade, it wasn't a very fun day.  Tired after moving and festival-ing over the weekend, the rest of us just kind of laid around with her.  The boy did keep to his exercise routine and his school schedule and I did work in the morning, but the afternoon was couch potato time, pretty much.  It was rainy and cold all day, which added to the lethargy.
