When Mandy and her mother are walking CeeCee on their little shopping trip they were filmed on the famous French Street at the Warners small town backlot. The entrance to Luke's diner from Gilmore Girls (2000) can be seen directly behind them as they start off down the sidewalk.
Mandy's mother makes a comment about the fact that when Georgie is middle aged he will have lost his hair. In The Big Bang Theory (2007) an older Georgie played by Jerry O'Connell has a full head of long hair.
