Paraphrasing A.J. Liebling again; Stephen Colbert does his schtick on two shows, his and Jon Stewart's, below.
Also worth noting: Jon Stewart somehow turned 9/11 into a porn segment that actually wasn't offensive, though it was shocking. His comments on the relative states of cleanliness of General Ricardo Sanchez, however, shocked us more.
"Eight more lives to give for his country!" We're not cat people, so we snickered a bit.
Update: NoFactZone is putting the pieces together and thinks Colbert might actually be seriouis. Well, that should liven up the debates! For both sides, really.
