A student's outgoing voice mail message quoting the theme to "Fresh Prince of Bel Air" led to a school lockdown in Ambridge, Pa. A receptionist from a doctor's office called to remind student Travis Clawson about an upcoming appointment. Clawson didn't pick up, so the call went to voice mail. The receptionist heard what sounded like a threat about "shooting" and "school" on Clawson's outgoing message.
