Perhaps the only thing worse than a call from the IRS is a call from the SEC asking you to "explain a few things." The SEC has launched an insider-trading probe at Sirius Satellite Radio and the first person brought in for questioning was gossip journalist Chaunce Hayden, who was "grilled for two hours yesterday by five SEC attorneys." Sometime before the October 6 announcement that Howard Stern was joining the company, insiders actively bought shares of the company in anticipation of a run-up in the stock price. (In the five trading days before the deal was announced, in fact, Sirius shares soared by 26%)

Hayden says that he's innocent - and that he's never even owned any shares of Sirius stock, which leads to the obvious question: who's next to face the SEC inquisitors?
