House: "You know, the down vibe in here is ruining my 'Charlie's Angels' fantasy." The ABC series Charlie's Angels (1976) featured three beautiful women who work for a private detective agency run by a mysterious patron known only to them as Charlie. More topically, the same year as this episode premiered there was a remake Charlie's Angels (2011), but was already canceled when this episode aired.
The name of the charity organization is the Phoenix Foundation, the same as the organization central to the show MacGyver (1985).
