The Waitress, who throughout the series is never named, is played by Charlie Day's real-life wife, Mary Elizabeth Ellis.
This episode is the second pilot of the show, commissioned by FX after they saw the original pilot that Rob McElhenny, Charlie Day, and Glenn Howerton made independently. That original pilot was remade as the episode "Charlie Has Cancer" later in this season.
At around 9 minutes, while recounting her dream to Dennis, Dee says "I had the craziest dream last night that I was in in Cleveland, Ohio which is really weird because I've never been to Ohio." Kaitlin Olson was previously a regular on seasons 8 and 9 of The Drew Carey Show (1995), which took place in Cleveland, Ohio.
Actor Chris Bain (VII) lists the show as one of his all time favorite TV series and the show served as inspiration for Bain's own television pilot Edinburgh Blue (2016).
Kaitlin Olson and Malcolm Barrett previously starred in Kelsey Grammer Presents: The Sketch Show (2005) together, which also starred Mary Lynn Rajskub who later plays Gail the Snail starting in season 5.
