A Public Service Announcement:

BANGKOK, Thailand - Thai police have issued a warning, but it seemed fishy: flesh-eating piranhas may be lurking in the capital's waterways.

... [The Thai police] had sound advice for anyone tempted to swim in Bangkok's murky waters and risk encountering carnivorous piranhas: "Especially, men should cover themselves well, otherwise they could be sorry for the rest of their lives."

This is definitely going to put a damper on next year's Songkran
