I too was very pleased to be introduced to Nardwuar, and kinda can't believe I'd never heard of him before. I especially liked how his call completely overshadowed the topic, because I had NOTHIN'! to call in with.
I just listened to the show again and STILL don't remember hearing any calls about the topic. That gives me two whole weeks to think about it and call in with a gem... and then get heave-ho'd.
