Todd Giebenhain makes his second appearance in the "Big Bang" universe as the sketchy salesperson of Meemaw's video poker machines. He previously appeared in the third-to-last episode of The Big Bang Theory (2007) - The Maternal Conclusion (2019), as Denise's creepy roommate.
The original title of this episode was "A Resident Advisor and the Riviera of the South". Biloxi, MS, where Meemaw and Dale bought the poker machines, is often referred to as the Riviera of the South.
When Mandy and Missy are watching Look Who's Talking (1989), Mandy mentions that the voice of the baby (Mikey) is the same guy from Die Hard (1988), which is Bruce Willis. Willis was also in The Sixth Sense (1999) with Haley Joel Osment, who is Emily Osment's (Mandy McAllister) real life older brother. They played Malcolm Crowe and Cole Sear respectively.
