As Jack Donaghy discovered last night, there are two reasons why Liz has made a complete 180 during the show's hiatus. The first (and funniest) reason is the Timeless Torches.
The Timeless Torches are a dance group made up of men and women over the age of 40 who perform at Madison Square Garden for WBNA Liberty games. Oh, Liz.
The second reason is a (SPOILER ALERT!) new romance with a man named Chriss, played by James Marsden. But back to the dancing! Here's the "making-of" video in which Tina Fey meets and rehearses with the Timeless Torches for the first time.
