Jimmy states that Kim's legal performance in defending Huell is like "Roy Hobbs knocking out the stadium lights". This is a reference to the climactic scene in the movie The Natural (starring Robert Redford) where the protagonist baseball character of the same name hits a home run into the stadium lights of his home field to win the final game.
The vital statistics listed on the Arrest Report for Huell Babineaux read, as follows: Date of Birth: March 20, 1968, Height: 5 feet 10 inches, Weight: 285 pounds.
The black and yellow shirt that Kai is wearing at the strip club is the jersey of the German football club Borussia Dortmund.
At the beginning of the episode, Kim asks Jimmy, if he'd be back from his trip to the Coushatta (Louisiana) post office on Thursday. Jimmy replies, "Thursday, yeah, unless we break down in Amarillo." While this doesn't register with Kim, his response was a callback to a stunt he pulled in the second season. Jimmy traveled to Texas in an effort to reach residents living in the Sandpiper Crossing located in Amarillo. He'd paid a Sandpiper Crossing driver to fake a bus breakdown, giving Jimmy the time to come aboard and solicit seniors.
Combined with breaking bad's total of episode's this would be the 100th episode if both shows episodes were combined
