Thanks to a new contributor, here's the second installment of Know Your Member (explained here). Like the first, this one is a little hard to believe. But I'm not sure how you could make it up, either.
Our boss was at the airport getting ready to board his plane on the way back to the district, when he called in a panic because he had left his eyeglasses and some other personal items in his DC apartment. He wanted an assistant to run to his house, pick them up, and deliver them to the airport before the plane took off. The only problem was that the assistant didn't have keys to the place.
Fortunately, there was one of those real estate key boxes on the door with a combo lock. Here's where things get a bit surreal. The Congressman didn't want to reveal the combo over the phone. It wasn't clear whether he thought someone might be wiretapping his calls, or someone in the seat beside him might be listening in (and know who he was, and where he lived, and memorize the combo, etc.).
Solution? The Congressman asked his assistant to guess the combo. Four or five digits, one digit at a time. After each guess, he'd give hints ("higher" or "lower"). And when he got it right, he'd signal in the affirmative.
