Read a written pun and it will make you smile at the thought of it, and puns make great text messages and tweets, but a visual pun is one you can share with your social media circle and the offline folks when they come over to visit.
And once you've seen how your circle reacts to those clever visual puns you've been sharing you'll want to find and post more, and believe you me they're out there...
But the real beauty of visual puns is how easy they are to create on your own, and since we always have a camera in our pocket nowadays we can snap pics of puns in the wild- or use our phone to take a screen shot.
