Don't forget to check the stool!

I had a dream in mid March that Senator John McCain was sitting at a bar. Being a huge fan, I was about to take a seat next to him when he looked me in the eyes with his friendly, charismatic smile and said, "Don't forget to check the stool!" I wasn't sure if he was being literal, because there was beer spilled on the seat next to him with a rat licking it up, or he was talking about everything in the bar branded in "Stool".
