When Jimmy (Bob Odenkirk) is walking in the mall, just before he sees the senior ladies, he passes the store Crazy 8. Krazy 8 is the name of one of Hector Salamanca (Mark Margolis)'s drug dealers (played by Max Arciniega) in Better Call Saul (2015), and also appears on the first season of Breaking Bad (2008).
In the episode "Uno" Jimmy estimates Chuck's share of the firm to be $17 million. In this episode Chuck estimates his share to be $8 million.
The jazzy number playing while Jimmy (Bob Odenkirk) is talking to the mall-walking ladies is a version of "Popcorn" by Hot Butter.
Boz Scaggs ("Lowdown") is playing in the mall where Jimmy's walking. On Breaking Bad, Walter White (Bryan Cranston) mentions how much he loved Steely Dan and Boz Scaggs.
