Ed Helms Sings Karaoke with The Muppets in Episode #4 - "Pig Out"

From Entertainment Weekly

The celebrities just can’t seem to stay away from The Muppets. 

Tuesday’s episode of ABC’s mockumentary hit delivered cameos from folks like Nick Offerman, Christina Applegate, and Liam Hemsworth, and that’s on top of the stars we’ve already seen: Josh Groban, Elizabeth Banks, Jay Leno, Lea Thompson, and Laurence Fishburne. 

Now, EW has a sneak peek at the next star knocking elbows with Miss Piggy: Ed Helms will encounter the gang when they hit Rowlf’s Tavern in the October 13 episode. 

Long story short: Everyone spends a little too much time letting loose at Rowlf’s bar, and the result is a sloshed round of prime Muppet karaoke. The Swedish Chef will rap, Sam the Eagle will slay Bette Midler, and Janice gets her first solo of the season…and that barely covers the set list.  "

"Pig Out"– The gang has an epic night out when they run into Ed Helms at Rowlf’s Tavern and they all perform their favorite karaoke jams, but Kermit is not pleased when no one shows up to work the next day. Meanwhile, Fozzie has an unfortunate accident during the show, on “The Muppets,” TUESDAY, OCTOBER 13 (8:00-8:30 p.m)
