this is my fav explanation from the movie mary and max
"Unfortunately, in America, babies are not found in cola cans. I asked my mother when I was four, and she said they came from eggs laid by rabbis. If you aren't Jewish, they're laid by Catholic nuns. If you're an atheist...
It's called banging it up.
Oh and no birth control or condoms should be involved.
And voila, approximately a year later you will have yourself your very own little ******** rat.
UGH. What am I talking about? Babies are ADORABLE.
I know it involves some birds and bees-
And a stork-
But then what???? Its all a little confusing, wouldn't the bird eat the bee? And is the bird the same bird as the stork, or is he a different one? Its all so confusing... HEHEHEHEHE ;)
