Spelling mistakes on internet forums can be quite humorous, specially when people are drunk or just stupid.
A site called "Something Aweful" featured a couple of questions posted on Yahoo answers and made a fun little animation of it.
How Is Babby Formed
If you think it's fake, here is the original question that inspired the story, you might need to see it to get the joke:
They need to do way instain mother> who kill thier babbys. becuse these babby cant frigth back?
"it was on the news this mroing a mother in ar who had kill her three kids. they are taking the three babby back to new york too lady to rest my pary are with the father who lost his chrilden : i am truley sorry for your lots"
And that's it, well I think thats the original one, and for the "how is babby formed" question, you'd have to filter through all of this
