In the tradition of Monty Python’s Complete Waste of Time, Penn &amp Teller’s Smoke and Mirrors two-disc set includes a couple of fake videogames (including one in which you can convince friends that they have destroyed your TV set), two mind-reading scams (accomplished by inputting key info, such as your friend’s birthday), and a hilarious bus-driving simulation in which absolutely nothing happens. But the replay value is a bit low, and things get weighed down by the ”Smoke and Mirrors” segment, a magic-themed role-playing game more tedious than clever. B
