Meet Mr. Knocky. He's a battery-free drum toy controlled by swinging two hand-held triggers. Not digging the sound of his plastic drums? No worries, you can swap them out for other percussion surfaces like a soup can or Pringles can. He is not recommended for use drumming on your nuts. Ha, like that's gonna stop you.
Keep going for two worthwhile videos of Mr. Knocky doing his thing.
Thanks to Paul, who's getting the band back together.
