Customer: “Do you have any calendars?”

Me: “Yes, they’re right behind you.”

Customer: *looks at several calendars* “This says 16 months. What does that mean?”

Me: “Well, it has the last four months of 2008, and then all of 2009.”

Customer: “But there are only 12 months in a year.”

Me: “I know. It has a whole year on it and then part of the previous year.”

Customer: “So what are the extra months again?”
