Two blonde friends were going on a trip to Florida. A neighbor told them
that they'd be fine as long as they paid attention to the road signs
along the way. But they'd driven just 30 miles when they saw one that
read "Clean Restrooms Ahead."

Two months later they arrived in Florida exhausted, having used up 86
bottles of Windex, 267 rolls of paper towels, and three cases of
toilet-bowl cleaner. Total restrooms cleaned: 450.
