It’s often said that it takes fewer muscles to smile than it does to frown. We’re not sure what whoever said that was trying to get at. Doctors are always telling us we need to work out more muscles to stay healthy. So, does that mean that people who smile are lazier than people who frown?

Whatever the meaning of that saying is, we’re pretty sure they weren’t referring to smiles like this Big Mouth Tattoo… If somebody were flashing you this creepy grin, you can be certain they are using every single one of their face muscles. Luckily, this temporary tattoo lets you show off your chompers without causing permanent strain to your cheeks. It’s a good look for your spooky clown outfit, or the finishing touch to your cheshire cat costume. Or, maybe you’ll just want to wear it around regularly, to show everyone what a “cheerful” mood you’re in!
