Many years ago, I was helping a friend move about six blocks in Manhatten in the middle of the night. The 100 year old rubber tree would not fit into the car, so we put it on a dolly and proceeded to his new apartment. About half way there, a police car stopped and asked what we were doing. After sizing up the officer, I commented that we were walking my friend's rubber tree. The officer asked why. I explained that the tree was 100 years old and incontinent. As a result, if we didn't walk it regularly, it would make a mess on the floor. After he got done laughing, the officer waved us on.
