Nothing like a good, old-fashioned bank run.

Anxious customers jammed the phone lines and Web site of Countrywide Bank and crowded its branch offices to pull out their savings because of concerns about the financial problems of the mortgage lender that owns the bank.

Countrywide Financial Corp., the biggest home-loan company in the United States, sought Thursday to assure depositors and the financial industry that both it and its bank were fiscally stable. And federal regulators said they weren’t alarmed by the volume of withdrawals from the bank.

Countrywide is toast. Someone pass the bacon.
