That's because, according to the Hollywood Reporter, 'The Wendy Williams Show' has been renewed -- again. The daytime talk show, which was previously renewed by Fox's owned and operated stations through 2012, has now been picked up by 18 of the 20 major markets, including affiliates owned by Lin, Tribune, Local TV, Sinclair, Raycom and Granite.

How great was it seeing Michael and Fi still sitting in that car? I like to imagine that they were sitting there for an entire week while we waited for the new episode.

Not that I didn't enjoy Michael's how-to on exposing covert security but I feel bad for the delivery guy. As if it isn't bad enough to get to the delivery and realize you've been pranked, this poor guy is also going to get the crap beaten out of him. No wonder Michael helps everyone he meets. He has a lot of bad karma to make up for.
