The smell test here is that swans are flying birds and a human is large(-ish) land mammal. Nature just cannot make a flying bird's bones strong enough because they have to be much lighter.

If we play conkers with each other's bones the swan will lose.

It's this thread, did you suffer HNception? :)

No, hit in the head by a black swan, thats all.
