The Krabby Patty Formula is written in random letters.
The Krabby Patty Secret Formula is revealed to have "humorous censorship", to keep viewers from discovering the secret formula themselves.
The title is also a reference to an old SpongeBob SquarePants holiday commercial. It was to promote a fake holiday album that Plankton made himself. At the beginning of it, an announcer said that on the albums Plankton made was called "Krabby Road".
When Squidward was working out this could refer to Wishing You Well when Patrick said to work out more.
In the German version of this episode, the episode is called Krabby Patty Blues.
When SpongeBob said "Hey Plankton can our first song be like this?" and he makes a deep alarm noise then a high-pitched screech has become a internet fad which a dreadful noise will replace the alarm noise and the high-pitched screech and it is called Hey Plankton.
Although multiple years after the movie, some fans thought this episode was set right after the movie, due to the movie ending with Plankton going to prison, and this episode started with him escaping prison. This is untrue because the movie takes place 30 years after the final episode, Plankton doesn't remember the formula, the Krusty Krab 2 is not seen or even mentioned, and no events or characters from the movie are mentioned or even reffered to in any way
The episode title is in reference to an album by The Beatles called "Abbey Road".
When Squidward tries to lift the weight and injuries his arm, SpongeBob can hear him scream in pain over the phone. However, just before this, Squidward had hung up his phone, so SpongeBob shouldn't have been able to hear Squidward's scream.
Squidward is seen playing left-handed when the group is warming up in the Krusty Krab, but later is seen holding the guitar right-handed outside the restaurant. This error also happens in Jellyfishing.
