Why Did Clear Channel Ban Harry Shearer?

I dunno.  Lemme think.

Obviously, the notoriously conservative radio monopoly banned advertising for Shearer's new album because it felt the album cover, pictured at right, cast unfair aspersions upon nose-piercings.

The funny part, though, is that Clear Channel is a radio monopoly.  Radio.  So it's not as though listeners would actually see the album cover.
