The Pac-12 coaches teleconference earlier today was going along just fine. Then Rush Limbaugh suddenly popped in to shout, "But since you're a liberal!" at Oregon State football coach Mike Riley just as Riley began to answer a question.

Limbaugh's radio show somehow got placed into the conference call by mistake. After only a few seconds, the operator's voice could be heard, too. She said she did what we would do if we happened to hear Limbaugh's show and couldn't turn it off. She muted him.
