During the scene where Danny is practicing his stealth moves in the hotel room, when originally aired, the soundtrack featured the classic theme from Mission: Impossible (1996).

The idea of stealing something and then selling a handful of forgeries as the real thing (for multiplied profits) is called the Mona Lisa Scam.
