Video: Why did Robert Plant give Stephen Colbert a hand-rolled joint?

It takes a lot to catch Stephen Colbert unawares. But singer Robert Plant did just that on Oct. 9 when he handed Colbert a well-rolled joint mid-interview.

“I brought you a little present from our stock room,” Plant said, reaching into his shirt pocket and revealing a hand-rolled joint.

“What’s that?” Colbert asked, quickly reverting to, “let’s find out what this is later, shall we?”

After the shock wore off Colbert’s face, he covered his own butt with a humorous cover-up: “For the purposes of my lawyer and my network,” Colbert said, barely holding in his surprised laughter, “this is a cigarette.”
