"Rally to Restore Sanity and/or Fear" (Kris Connor/GETTY IMAGES)

And to prove how much he’s listening to those instructions, the Super PAC’s latest ad attacks...Colbert himself.

“Come on. Why is the T in his name silent? What else is he silent about? Letting murderers out of jail?” sneers the ad, narrated by Samuel L. Jackson.

Anyway, the ad also urges people to vote for Herman Cain. In case you missed it, Colbert is holding a rally in South Carolina a day before the state’s primary featuring Cain as a special guest.

Colbert promises that the rally — called “The Rock Me Like a Herman Cain: South Cain-olina Primary Rally” — will be even better than his “Rally to Restore Sanity and/or Fear”in Washington last October, if only for the absence of Jon Stewart.
