You may be a reference librarian if...

...if, on your drive in to work on a Saturday morning, you stop at a red light and watch a man pushing a twin baby carriage across the street...but instead of babies, a case of beer is in each slot.

And you think to yourself, "I bet $10 that I'll be seeing this man at the library later today."

And you are now wondering how to pay yourself $10 for the bet when he walks in the door.

At least the carriage is outside.
