The hippopotamus is a ridiculous looking animal with its absurd size, bizarre proportions, and odd features.
So it is at the end with pregnant women, and I can write that because I am one.
At the very end of pregnancy, the woman usually assumes a shape something like the grotesque female imaginings of R. Crumb. (No, I'm not a fan of his, but I have seen Crumb.) Or, as I said to my husband this morning, something like a series of orbs in a sock.
It is a good trade though. This transformation is usually temporary, and you get a kid in the end.
Unlike the hippopotamus.
