We have so much on our minds that we couldn’t pick one topic for today — we’re going with three! Strap in.

First: a failed bill from the 1900s that proposed hippopotamus ranching in the U.S.

Then: an initiative to save humanity by storing poop in a vault

And finally: orcas teaching each other to sink boats.
