Backward-Kneed Geese are usually found circling groups of confused chocolate easter bunnies, speak Oinkery and can only count to green. they can be sometimes be confused with Mustard Drooling Cane Toads, who like to harass small crowds of slaters on weekends.
There is only one way to defeat the Geese... Slap them on the nose and say; "FUCK YOU GOOSE, YOU BACKWARD WALKING FREAK"
Because its common knowledge that Backward-Kneed Geese have severe self esteem issues. So aim for the fact that they're not in the least bit a lovely fruit basket or even a set of Porcelain Cat Bookends, and they retreat quite easily back to their tents.
But watch out, they know where you live.
