Me, in August:

“‘Corporations are people’? In this little figure of speech, wouldn’t that make Mitt Romney a metaphorical serial killer?”

The new ad from Stephen Colbert’s Super PAC:

“As head of Bain Capital, he bought companies, carved them up, and got rid of what he couldn’t use. If Mitt Romney really believes ‘corporations are people, my friend,’ then Mitt Romney is a serial killer.”

For the record, I don’t actually believe the likely Republican presidential nominee kills people, his treatment of dogs notwithstanding.
