Garfield dreads the day upon finding out that is Monday. He does whatever he can to avoid bad luck.
One morning, Garfield wakes up Jon with an accordion, expecting him to make blueberry pancakes for breakfast. After seeing a group of instruments Garfield intends to play if he does not get up, Jon reluctantly heads to the kitchen. Later, Garfield gets a ladder to pour syrup on his "short stack" of pancakes. Jon gets a box to send things to his pen pal in Samoa, then checks his calendar. Garfield is not concerned with what day it is until he hears that it is Monday.
Garfield daydreams a trailer involving numerous bad things to be anticipated on Monday. He then takes Jon's watch, setting it to go off when Monday is over. He goes to bed, hoping to wait there until the day is over, only for Jon, not understanding Garfield's concern, to force him outside. Garfield tries to remain calm as he figures the day will be turn out to be fine. He is then hit with rain, a "splut" pie, and a piano.
Returning home, Garfield finds Jon's package to his Samoan pen pal. He plans to send himself to Samoa in an attempt to evade Monday. After getting himself inside Jon's package, he goes through the process of being mailed to Samoa, which includes several painful parts, such as being thrown into the mail truck and getting squished inside the cargo plane.
After the package arrives in Samoa, a cat takes it inside his home and opens it, with Garfield desperately emerging out of it. Garfield becomes thrilled to see that Monday is over, only for the other cat to inform him that, due to being in a different time zone, Monday is only getting started in Samoa. Garfield runs out of the house and looks for safety. He finds a door marked "GORSH", which is Samoan for "splut", and opens it, getting hit with a pie as a result. Garfield sadly confirms that it is still Monday.
