House is reading an issue of "Stiletto: Warrior Queen of Space," a comic book that was a MacGuffin earlier this season in episode "Known Unknowns," and was referenced again in the episode "Wilson."
At around thirty minutes, House affects a French accent and behaves much like the fictional detective Hercule Poirot (who is Belgian Walloon - who speak a dialect of French).
House and Wilson are waiting up to discover who has been pranking them, and House is holding a cricket bat, a reference to the fact House's actor, Hugh Laurie, is British.
