It was bound to eventually happen, and I'm not so surprised. I just find it ironic in terms of timing as my Dad and I just got back (literally as of last night) from a trip to California where we attentended a taping. I guess those mugs are now collectibles.
What puzzles me is the choice of Fallon. I thought his ratings weren't necessarily good, at least when he started and his format is different. But then maybe different is what NBC needs now. They did toy with different formats, including a variety show format, before they settled on the current one we know of now.
