A CNN segment that followed a group of marijuana smokes while they rode around Denver on a 'cannabus' and later joined a 'Puff, Pass and Paint' party surprised a number a viewers - and host Anderson Cooper.
The 50-year-old silver fox stopped by The Late Show With Stephen Colbert on Tuesday, and spoke about his night in Times Square with new co-host Andy Cohen, who replaced Kathy Griffin after she was fired by the network.
And when the topic turned to Randi Kaye's night with a handful of stones, Cooper said: 'The whole thing surprised me as much as anyone else. I have to tell you.'
He said this through a fit of giggles, having previously pointed out that recreational marijuana use is in fact legal in Colorado.

Colbert got the ball rolling early in the interview, asking: 'Do you still have a contact high from Randi Kaye? You guys got a little teasing.'
After pointing out the legality of the substance, Cooper added; 'We are grown adults. And she did not smoke.'
His surprise meanwhile seemed to be with the last party Kaye attended that night.
'She ended up at a paint party where I guess this pot bus ended up at a paint party where for whatever reason people riding around getting stoned all night want to end up painting in day-glo colors.'
