Threatening to kill people like President Obama and NYPD Commissioner Raymond Kelly isn't what made Crank Yankers a hit. On Sunday afternoon, police arrested 18-year-old Bronx teen Jonathan Avalos for calling 911 five times that morning and making the threats. Police sources tell the Daily News he's undergoing a psychiatric evaluation, because standing outside an Obama event with a gun is one thing, but crank calls will not be tolerated.
