The Staircase Implementation - S3-E22

Character mistake: When Howard says they should put the time machine into the elevator in 1-14 "The Nerdvana Annihilation", Leonard states the elevator had been broken for two years, but in this episode, we found out the elevator broke seven years earlier. (00:03:10)
