My flatmate and his girlfriend
went to Glastonbury last year. She'd purchased some of those "whizaway" things that allow women to pee standing up (therefore avoiding bodily contact with the soiled loo surface).

After getting the hang of them, she merrily went to the loo. Looking through the hole, she saw a stream of urine coming down from the cubicle opposite her. Quick as a flash, she and her mystery opponent were quickly playing "swordfight" with their urine streams, giggling away to themselves.

She was still giggling when she rejoined her boyfriend, so he asked what the joke was. When she told him what she'd been doing, he was absolutely aghast! Apparently she'd broken a cardinal rule, and that she should "never cross the streams!"
