Them finding the fly in the supermethlab in Breaking Bad. I remember it was late at night and my roommate and I both had stuff to do the next morning, so we said we were only gonna watch one more and then we would be done for the night. It ended up being that episode. We felt so cheated that it was an hour of Walter and Jesse trying to kill a fly that we made a special exception and said that the episode didn’t count and that we would watch one more.
