Opens What?!
You can’t see it in this photo, but the joke is that if you locate this evil dog from another dimension, you should notify the Ghostbusters. Those guys that look after stuff like this, as well as enormous marshmallow men. You could, however, always keep Vince. He has a lot of useful skills, including the ability to open portals to other realities. Who wouldn’t desire a dog capable of such feats?
Missing Cat
The oldest trick in the book: take a photo of a wild animal and create a lost sign for it, implying that a frightening beast is loose in the neighborhood. That terrifying beast should be known as Mr. Tiddles, since who wants to be mauled by a cat with a name like that? But, if it responds to pain cries, doesn’t that mean you can ask it to stop after it has wounded you? We suppose you’d have to survive the initial strike first, which is a dangerous idea when dealing with a lion.
