3. Troll Foot
For a guy nearing 70, you wouldn’t expect Danny to embrace social media so profoundly. And yet, he does — he introduced the world to “Troll Foot.” Basically, he takes pictures of his gnarled, hoof-like bare foot in unlikely scenarios — like, say, backstage filming an episode of "Yo! Gabba Gabba" or courtside at a Lakers game or posing with the Jonas Brothers — and posts them on Twitter. It’s bizarre and pointless and therefore genius.
