At around 0:58, the same nurse and patient walk by in the background,
In the scene where House and the team are looking outside for the cat, House fakes getting sick and takes a drink from the cup he's holding. He them spits the contents of the drink - cranberry juice - all over Dr. Kutner's shirt and right side of his lab coat. Right after, Dr. Kutner is shown with the juice on his shirt and on the left collar of his lab coat, the right side is pristine.
At approx 20 minutes, House is sitting with the cat on his lap and a cigar in his mouth, apparently parodying James Bond's nemesis Ernst Stavro Blofeld. However, the Bond villain he quotes is Goldfinger: "No, Mr Bond, I expect you to die!" Furthermore Blofeld's cat is always white and Blofeld does not smoke cigars.
Taub mentions that he had cheated on his wife with the daughter of one of his partners. However, when he first learned about the affair, it was said that he had the affair with a nurse.
