Christopher Dorner Standoff — Newscast PRANKED By Howard Stern Fan

It was only a matter of time … but a Howard Stern fan managed to infiltrate the Christopher Dorner news coverage by posing as an expert … and PRANKED a Los Angeles TV station live on the air.

The caller got through to KCBS-TV moments ago claiming to be a State Fish and Game ranger named Mike Taugher … and he was SUPPOSED to recap the events leading up to the shootout.

It started out pretty believable … but when the caller name-dropped Ronnie The Limo Driver (a Stern regular) it was pretty clear CBS has just been hoaxed.

… well, obvious to everyone but the anchor … who continued engaging the caller until he told her it was a joke and then called her an “idiot.”
