I agree with Vald that Beat The Geeks was awesome and needs to return. Also, I'm with Sublex that GSN should just be all the old black and white classics. When I still lived in the US 5 years ago, I loved catching Password and What's My Line in the middle of the night and revelling in that much simpler time when people still smoked on TV.

Then I realized everyone I was watching was most likely dead by now, but it was still fun. Bring back the classics I say!
