Invite anyone from the Irwin family over, and you just know you're going to get some animal action.
Jimmy Fallon had Animal Planet host Robert Irwin, son of late Steve Irwin, on The Tonight Show, and he brought a lot of furry cuteness on set with him.
Fallon didn't seem that into the cute baby animals, though. Even the cutest baby otter you've ever seen had Fallon visibly uncomfortable.
Seriously though, that baby zebra.
