The Best Children's Book

So, my sister sees this children's book called How Big is a Pig?

She flips through it, and it's filled with pics of animals, and Nora likes animals, so she buys it. When she gets home, she reads it to Nora. There are dogs, hens, frogs, etc. inside, and Nora seems to like it, so it seems like a pretty good book. But then, at the end, it reveals who the biggest pig of them all is... (Click the pics to make them bigger.)

Yes, MOMMY is the biggest pig of them all.

Needless to say, my sister threw the book away. I pulled it out of the garbage, however, so I could scan it and share it with you.
