I really didn't think House would make an appearance at PPTH, but here he is at Lane's bedside, asking him to sing "My Bonnie." When I was little, I thought the song was called "My Body" and wondered why some guy's body was floating around in the ocean and needed fetching, or if the song was directed at someone who stole some guy's body but somehow left him alive and with just a head with a mouth so all he could do was sing about it. Lane doesn't see how singing will prove anything, but House says that Lane had better sing and stay on the beat, or else he'll have to have a risky skull-opening procedure. Martha explains that if Lane is having blackouts and his brain is compensating for them, Lane wouldn't even realize it, and everyone else would just think he was slow to answer questions. But his brain can't compensate for a pre-set rhythm in a song. House starts up the metronome and tells Lane to sing. He does, and just a few verses in, he starts pausing for a few seconds at a time, then resuming where he left off like nothing happened. When he finishes, he sits back and thinks he did a great job. Martha informs him that he did not. "That was brilliant," she then tells House. I think Martha has another crush! Her prefrontal cortex is beside itself this week! "Yeah," House says sadly on his way out of the room.
