In this ep of "The Big Bang Theory": Sheldon's usual barber is hospitalized and since the nephew there doesn't have the "haircut records" (obviously thought up by Sheldon's mom for her son's benefit when he first moved to California), Sheldon bolts. So he spends several days blowing it out of his eyes before reluctantly agreeing to let Penny do it. Meanwhile, Howard gets his astronaut training in Houston which he tells Bernadette about online. He manages to survive without food or water and manages to also endure weightless vomit! Another very funny ep of "The Big Bang Theory" this was especially when Sheldon starts playing the bongos for no particular reason or Penny-who's never played chess before-beats Leonard at it! So on that note, "The Werewolf Transformation" was another very funny ep of "The Big Bang Theory".
