If we learned anything from the O.J. Simpson trial, it's that rhyming is very effective. If it's catchy enough, it'll stay with us forever. So it's no surprise that Stephen Colbert is on board the Herman Cain train after seeing a rhyming commercial for the Republic presidential candidate on 'The Colbert Report' (Weeknights, 11:30PM ET on Comedy Central).

"When it comes to a presidential candidate, I look first for an easily rhymed name," Colbert explained. He then went on to show us just how effectively Cain's name could be rhymed.

"I am insane in the membrane for Herman Cain. He's hotter than propane, though he could use some Rogaine. It is Herman for sure, man. He drinks tequila and leaves the worm in. The other candidates are squirmin.' I've determined he's not German."
