Recently, Know Your Meme sat down with Justin Kuritzkes, whose Potion Seller video skyrocketed him into meme stardom back in 2011. In the video, Justin is playing with his computer's photo booth function while performing a dialogue between a knight about to head into battle and a potion seller who refuses to sell him potions because they're "too strong." After the video was posted, it inspired numerous memes, animations, remixes and tributes.
