And last night - what WAS that??? I have no idea who those two "rappers" were, but it looked like she pulled them off the street somewhere.
They were like two teenagers who just smoked their first joint (the one on the end had to be high, right??), and were just giggling over everything and thinking they were the shit because they smoked it. I give a ton of credit to Russell Brand (who I'm normally not a big fan of) for putting in the effort to try to make something of their godawful contributions to the show.
My assumption was that they're trying to get more attention to their rap career and they know someone connected to her show who was able to talk Kathy (or someone else behind the scenes) into putting them on an episode.
