Great article on vintage-style phreaking in Rolling Stone. The article includes this alleged exploit:

Last year, during the presidential campaign, Weigman heard a YouTube video of Mitt Romney’s son Matt dialing his dad. Weigman listened closely to the touch tones, deciphered the candidate’s cellphone number — and then made a call of his own. “Mitt Romney!” he said. “What’s going on, dude? Running for president?” Weigman says Romney told him to shove the phone up his ass, and hung up.

Well, well, well. Mitt Romney has a thing for phones up his ass. Who knew?
