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...
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 ;)
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.
