Here in Elk Snout (the fictional small Oregon coastal town featured in the 1987 Kurt Russell/Goldie Hawn movie Overboard), things are different, all right.
From an article in the Oregonian about use of fake urine in drug tests, this information from a county Dept. of Community Justice spokesperson:
The tampering includes people who dilute their own urine and tricksters who turn in a range of substitutes. “For example,” she said, “someone tried to pass off a sample of elk urine as their own.”
