Colbert brought the Drug Policy Alliance's Ethan Nadelmann back for round 2 last night. For those of us who've grown accustomed to seeing Nadelmann masterfully control the stage, it's kinda fun watching Colbert box him around. You don't really get to say much on Colbert, but if you keep a straight face while he massacres you, it's possible to come across looking pretty good.

One question though: what's up with the lava lamp!? Sources familiar with whether or not there's a lava lamp in Ethan's office tell me there isn't. Did Colbert put it there? Following his attempt to feed Doritosâ„¢ to MPP's Aaron Houston, I certainly wouldn't put it past him.

Of course, when Steve Colbert subjects reformers to relentless and preposterous stoner stereotyping, at least it's a joke. When the head of the UN drug office does the same thing at a serious event, it's a lot less funny.
