When Tracy Jordan calls Betty White to try to scare her to death, she's reading a book called "From Peanut to President," written by Jack Donaghy's biological father, Milton Greene (Alan Alda). This book was first referenced in Kidney Now! (2009) when Jack mentioned Milton was writing a three-volume biography on Carter, and if he got the kidney transplant he needed, he could live to finish it.
Yet again, the melody of Jenna's hit song "Muffin Top" returns as a tuba theme for darker sequences like when Tracy tries to bludgeon Jimmy Fallon to death with a claw hammer.
Jack McBrayer, who plays Kenneth Parcell, portrays a man and a woman (presumably his relatives) at the comedy club in his hometown of Stone Mountain, GA.
The drive through restaurant Fatty Fat's Sandwhich Ranch Liz and Jack go to in Georgia is actually a drive through convenience store called Dairy Barn, which was a chain of stores located in Nassau County Long Island.
Kenneth's hometown of Stone Mountain is often suggested by the show to be a rural small town in western Georgia. In reality, Stone Mountain is a suburb about 15 miles east of downtown Atlanta.
