Must-see morning clip: Sanjay Gupta has gone over to "the dank side"

CNN's Dr. Sanjay Gupta -- or "Ganjay Supta," as Stephen Colbert has taken to calling him -- has "gone over to the dank side." The doctor has reversed his opinion on the legalization of marijuana, telling Piers Morgan that "I think we've been terribly and systematically misled in this country for some time, and I did part of that misleading."

"Wait a second, we were misled by a cable news doctor?" joked Colbert. "Next, you'll tell me that I can't get directions to my cousin's house from Fareed Zakaria GPS!"
