Many folks inform me that the reason Penn Jillette may not be tweeting these days is that he's in New York taping his participation in the next season of Celebrity Apprentice. Do they not let those people tweet about matters, even those unrelated to the show? Perhaps.
In any case, I don't believe Penn & Teller are splitting up. I'm just kinda curious what it is that caused Robin Leach to leap to that conclusion.
