  • weird

  • "Oh emotional outbursts take more that 1.5 volts, now we know that."

  • @georules I think that the zinc from the nail gets absorbed into the potato, and causes health problems if ingested directly (as opposed to the very small amounts that are necessary in a healthy diet)

  • he sounds like weatley from portal 2 :D

  • I would like the reaction explained so I know why the potato is not healthy to eat anymore -- I don't think it goes without saying.

  • many potatoes were harmed during the production of this videos

  • This guy laughs very funny on 2:01. Look for yourself

  • pay the electricity bill with potatoes

    

  • lol fit 9 of thoses in a flashlight
