AHA! Now I get it. If one of us kids was eating too much, my mom would always say "how can you get that much food into you? You are eating like you have hollow legs!"
My mom was the mother of TWINS! I think she was telling us in her own way that when she was carrying the twins they were in her legs.
What happens if it is triplets?

You know, that would be a great movie: cannibalistic embryos.
"Mrs. Jones, you have a healthy pair of baby boys. They're eating you from the inside, Now, don't be concerned. Thi=s is a pro life state, so we'll do everything we can to make sure that they keep munching away until there's nothing left of you. "
Brilliant!
