I was once in a limo with someone who had to go so bad after we were stuck in traffic for three hours that she peed into someone's big gulp cup

The one and only time I've been in a helicopter, one of my fellow (female) passengers had to pee into a Coke bottle. I mean, I can't even pee and aim into that little cup for urine testing, let alone manage a Coke bottle in a moving airborne vehicle, gosh.
