Jake receives an inheritance from his uncle of 1 million Blockbuster shares. The bullpen groans in disappointment as Jake asks what happened to Blockbuster. However in Season 1 episode 21 (Unsolvable), when Jake is trying to convince Terry to work on the unsolvable case by explaining how things have changed for them to be able to solve the case, he mentions there is no more Blockbuster.
In every other episode Cheddar is orange and white, in this one he is also black.
When the squad learn that Jake has inherited 1 million shares in Blockbuster Video they all groan. In April 2016 when the episode first aired, Blockbuster Video stock had a value of 0.010 USD per share, meaning Jake had actually inherited $10,000.
Jake states that the average foot speed of a corgi is 10 miles per hour. While corgis can, despite their small size and short legs, reach running speeds of up to 25 mph, their average walking speed is less than 3 mph.
Early in the series, Jake mentions to Terry that Blockbuster is gone, thanks to the rise of streaming services like Netflix, and they'll have to just let it go, because it's not coming back. However in the opening scene Jake inherits a million Blockbuster shares from a deceased relative and is dismayed to discover that Blockbuster is over, because he still has a Blockbuster card and thought their business was booming. He yells out, "What happened to Blockbuster?!"

At 9:19 Charles turns and hits the wall and it shakes, clearly indicating it is a set wall.
When Charles is on fire and runs and falls onto the table padding can be seen on Charles back and legs after he falls.
When the whole squad dresses in Holt's clothing to try to lure Cheddar, Terry is seen wearing clothing that fits his frame. Terry Crews is several inches taller and more than 40 lbs heavier than Andre Braugher. His arms and chest, especially, would not fit into clothing meant for a man Holt's size.
Charles's leg hair is said to have been burnt off by the space heater in Captain Holt's living room, and he hopes it grows back by Speedo season. In The Mole (2014), it was established that Charles has no leg hair. He has worn cheap pants all his life and has been chafed smooth.
At around 04:50, as Amy is wrestling with Cheddar she says "Oh, my stupid allergies" but her mouth does not move.
At 14 minutes and 29 seconds as Jake and Amy enter the park to find Boyle, a California Highway Patrol Ford Explorer can be seen driving down the street in the background.
