The Irish Pub Formulation - S4-E6
Corrected entry: Sheldon is playing an online game he found. He yells to Leonard "I'm trapped in quicksand, the axe is dragging me down." Leonard then tells him to "Drop axe." Shortly after, Sheldon heads to bed, but he comes back saying "I know how to get the bucket. I can turn the axe around and use the handle to reach it." However, he does not have the axe as he has already dropped it. (00:06:05 - 00:07:45)
Correction: Sheldon is playing an old text and type game, many of which have only one way to beat them, so once Sheldon died, he would be sent back to the start, eventually reclaiming the Axe.
