I don't get it at all... don't birds and bats have hollow bones so they can fly?

haha see thats the joke. They always say "birds have hollow bones so that they can fly"
but the truth is, we all have hollow bones. It's just that birds bones are very very light. But everyone has hollow bones.

Maybe you have to be a bio major- I donno
