This morning, after dropping me off at the train station, Sarah dropped Barney off for his mandatory neutering (the shelter where we adopted him will 'prosecute' us if we don't do it by December something or other). Also this morning, the bus had a distinct urine smell. Wait a minute... Somebody call the AP!!! Neutering your dog causes city buses to smell like pee!!! I've made a discovery!!!!

Correlation does not mean causation. Call the AP.
