On the DVD, when the second theme song plays, the backup singers' line "Lots of spaghetti" is misinterpreted by the subtitles as "I'm scared."
In the scene with the airplane upside down, Garfield has no stripes.
Jon: (Knowing that Garfield has landed him in the South Pole) Well we just have to spend our vaction here rather than to riding on that plane again. (sees an eskimo) Excuse me, do you know where can I find a hotel?
Al: How do you do? (Shock to see him) Name's Al Swindler!Hop in on my dog slegde.
Jon: YEAAAAAAAAAAAAAA! (Carried both Garfield and Odie and rode back on the plane and flew off)
Al: Sheeeesh!It's getting tougher these days to get a single buck.
Jon: What do got for $70?
Guy: 4th Class Cargo. We let you squat in the baggage hold eating pretzels, while the stewardess shows you her vacation slides.
Jon: That doesn't sound terrible.
Guy: Some restrictions aply. You must fly on Groundhog's Day and stay at least 6 years. You must be dressed as a pigeon and be named "Larry".
Garfield: Just because I can't talk, [Jon] never listens to me.
Jon: Aren't you forgetting something?
Al: No, I've got my parachute.
Jon: The plane has only one wing.
Al: That's not enough?
Jon: No it's not enough! You need two!
Al: Complain, Complain! Next thing I know you'll be expecting landing gear.
Garfield can fly an airplane.
RESPONSE TO ABOVE: We knew Garfield couldn't talk in the first episode.
We learn that Garfield can't actually talk.
From this episode until Season 7, "Friends are There" intro is replaced by the well-known "We're Ready to Party" intro.
