Liz is acting unusually cheerful and Jack sets out to find out why. Meanwhile, Jenna is finding new popularity as the mean judge on a televised singing contest for little kids, which Jack also finds himself involved in...
The Series/30Rock episode "Dance Like Nobody's Watching" contains examples of:
- Affectionate Parody: Kidz Got Singing is one of American Idol, with Jenna playing the role of Simon Cowell.
- Cliffhanger: We don't see the face of Liz's new boyfriend at the end of the episode.
- Did You Just Have Sex?: At the end of the episode, it's revealed her good mood is coming from the company of a new boyfriend...
- Harsh Talent Show Judge: Parodied. When Jenna is cast as one of the judges for the show "America's Kidz Got Singing", she acts as the mean in the Nice Mean And In Between trio of judges. However, rather than provide any kind of constructive criticism for the child performers, she cruelly and blatantly insults them, even telling one child to 'jump back up [her] mother'. When Jack begins feeling empathy for the kids, he briefly has Jenna treat them nicely, though this largely consists of her struggling to twist her rude remarks into something only vaguely resembling a compliment.
- Implausible Deniability: Jack hears her baby Liddy say "mommy" and mishears it as "money". Once is understandable. Then she says it two more times and he still hears "money".
- Love to Hate: Used word-for-word by Jenna to describe her appeal on Kidz Got Singing.
- Mistaken for Junkie: Pete assumes Liz is using some drug to become more mellow.
- Red Herring: Jack and Tracy follow Liz and see she's attending a dance exercise club; her new good mood is explained! It's only on the ride home we see the real reason for her good mood.
