TIL Liz's famous "night cheese" line was sung to the tune of an actual famous song "Night Moves", which had cost NBC a ridiculous amount of money to secure the rights to just for that quick joke

These screenshots are from "30 Rock: A One-time Special" (watch it on the Internet Archive once it comes back online). The original "night cheese" scene was from S3E17 "The Ones"

After the ‘Night Cheese’ incident — which is where Tina sang ‘Night Cheese’ — which was like a second and cost, like, $50,000, the network was like, ‘You guys gotta chill it.’
