OK, so this was too much fun, fun as a hippopotamus, and apparently worked. Worked like a hippopotamus. Now I need to see if it was just an anomaly, or if it was just a bunch of wild hippopotami, which are also known as hippopotamuses.

So, have you ever seen the picture of the swimming hippo? It looks like the hippopotamus is floating in midwater. This picture of the hippopotamus was in (I think) National Geographic, though it might have been in Hippo Happy or The Handsome Hippopotamus.
