Hell Hath No Fury...
...like hung-over swans.
I used to live opposite a pub next to a waterway, and swans would congregate there. If you decided to eat or drink outside when the swans were around, you were taking your life into your hands - they would relieve you of your food, and help themselves to your drinks.
They would then sleep it off for a while, but invariably woke up all bad-tempered and fighty.
They weren't in the same league as Mister Asbo though.
