Factual error: House is playing 'Metroid: Zero Mission' on his Gameboy at various times. The Metroid series does not feature space monkeys, nor are there distinct levels. The sounds coming from the game in the show do not match it in real life, and Samus morphing into a ball is most definitely not a failure state.

Continuity: When Allison talks to Robert about her sexual drives, she places her hair behind the ear, but seconds later the hair gets loose, but only in the front shots. In the back ones it remains fixed around her ear. Submitted by Sacha
