Jon, Garfield and Odie are driving to see Jon's cousin George for dinner. At first Garfield does not mind George until Jon tell him he's a D.J causing the cat to scream, panic and try to escape. Inside George's house, George shows the dinner; Celery Stick, Mashed Potatoes and Gravy, Steamed Carrots, Creamed Corn and Swedish Meatballs all while reciting the countdown of the top 5 songs. During dinner George tells Jon that he's been promoted to manager of the station. Right now he's been looking for day hosts and tells Jon he has a good voice and offers him to be a D.J much to the worry of Garfield and Odie.
The episodes interrupt with a message from the NIDJP (National Institute for Disk Jockey Prevention) with Garfield hosting. Garfield explains how certain people take that step and become D.J. To prove it he shows a normal person playing a record player and then shows the next slide showing that same person as a Disk Jockey who's much more insane and hyperactive then what he usually was. Garfield then tells the viewer to not let them become D.Js and returns to the episode.
The next morning Garfield wakes up and goes to the kitchen only to find out breakfast isn't served and Jon is not here. While Garfield attempts to find Jon, Odie directs him to the radio he was listening and the two hear Jon's voice. To his horror, Garfield has found out that Jon has become a D.J. As the radio goes on a commercial break, Garfield tells Odie that Jon will come home soon and they'll get his attention. Jon later comes home but he's focused on his new job so much that he forgot to feed his pets before leaving. Odie whimpers and Garfield agrees that they want the old Jon back so they follow him to the station to set things right.
At the station, Jon is playing more songs with George commenting that he's beautiful only for Jon to comment back while Garfield watching is gagging. Just then Mr. Frump of Frump's Clothing arrives. He tells Jon to do a good job on his commercials and no insults. Hearing this Garfield gets an idea of a dirty trick, he notes that it will not be pretty but it is something he must do. He goes to the typewriter and writes up a script for Jon to read and soon replaces the original script with his script. This script humiliates and insults Frump's Clothing which Jon does on the radio. Enraged, Frump tells George to fire Jon which he does and Garfield tells Odie that their work is done.
Outside, Garfield and Odie are waiting for Jon who just recently got canned by George. Once outside, Jon realizes that he's a normal person again and apologizes to Garfield and Odie for forgetting to feed them. Jon makes up by getting a big lunch while Garfield and Odie comment each other that "they're beautiful."

- During Garfield's disc jockey PSA, "the boss sounds of The Boss" is mentioned, likely a reference to the nickname of Bruce Springsteen.
- The songs that Jon plays on the air include "Don't Evict Me From Your Heart" by Vinnie and the Landlords and "I Want To Hold Your Pancreas" by The Surgeons (spoof of "I Want To Hold Your Hand" by The Beatles).
