Actually, the best thing since sliced bread is Betty White (she was the best thing before it, too), but considering how much she loves animals I'm willing to bet she'd let these tortoises have that title. Because today we've all learned that there are precious few things more adorable than a tortoise dressed as a shark, a ladybug or a hamburger, in the world. You know what? You may just want to bookmark this post to come back to on those days when the dog bites and the bee stings (I told you not to try to put that bee in a Hamburglar outfit!). Tortoises will always help make you feel not so bad.
Or you could purchase these costumes from the Mossy Tortoise Etsy store and enoy them in the comfort of your own home. There are options.
