I don't know if anyone has heard, but tonight on ABC there was a Muppet Marathon in which 4 episodes of the series were all aired in a row: "Pig's in a Blackout", "The Ex-Factor", "Going, Going, Gonzo", and "Single All the Way".
A couple times, they aired a promo a few times announcing the series' return on February 2. There wasn't much mentioned about the plot, but there are a couple things I saw and thought would be worth mentioning here. For one thing, it looks like Miss Piggy just got dreadlocks. Secondly, in another shot, I thought I saw a glimpse of a certain character that we've been really wanting to see on the show...OK yes, I'm referring to Walter!
