In the name of SCIENCE I ask this question:
Has anybody actually had their arm broken by a single flap of a swan's wing?
Or it this simply black propaganda put about by angry geese to get the heat off?
FACT: Early drafts of Tchaikovsky's classic ballet "Swan Lake" where called "Angry Goose Rampage", until an assault by "unknown hissing, flapping thugs who fetched me a nasty peck" forced the Russian composer to change the title. "Also, cheaper car insurance and compare waterfowl."
The Fragrant Mrs Duck once had her arm swallowed by a goose. Goose bites can be very nasty, you know.
