KPCC should have known they were asking for trouble when they put up a giant billboard next door to fellow public radio station KPFK. The press picked up on the story, as did an anonymous graffiti artist, who felt inspired to modify the advertising:

Photo is via KPFK host Lalo Alcaraz. Neither he nor the rest of the station’s staff had anything to do with the graffiti. But they were amused.

The graffiti has since been removed, and the billboard is back to advertising for KPCC. A photo of the unmolested signage is after the jump.

The red building next door to the billboard is the KPFK headquarters.
