Return My Alien Ball

In "Family Day" from "Resident Alien," Harry Vanderspeigle kidnaps the dog that Sahar has been dogwalking as part of her business, Murphy, leaving her one of these saying that if she ever wants to see her again to return his alien ball. Like a lot of things about human society, Harry apparently doesn't quite get the point of a cut-and-paste note, as it's obviously identifiable from the contents as coming from him, even if he hadn't signed it "-Alien."
