Completely irrelevant and honestly not nearly as amusing as I think...
I was looking at screencaps (like you do) of Deception, I think... and it looks like House is playing Sudoku on the computer. The reason I find this amusing is that JMo said on some feature that they had all gotten addicted to the game (thanks to Hugh) and now were not allowed to have games at work. Hee. Teehee.
