Biggest plot hole of them all
The plot hole I am talking about basically crumbles the whole movie and destroys any believability this cartoon-style story would have had otherwise. Which is still not much..
So, Jerry's problem is that he needs money.
Jerry is married to a sweet, kind-looking, friendly woman, whose father is incredibly rich.
This woman's father wants to take good care of his daughter.
You put these three things together, and no matter how you slice it, you arrive at the following conclusion:
Jerry could ask his WIFE (who is supposed to support her HUSBAND) for pretty much any amount of money, or at least a reasonable amount, and there's NO WAY she would just coldly deny him. When that sweet, loving (?) wife looks into those big, beautiful eyes of her beloved husband, is she _REALLY_ going to deny any request like that, especially if Jerry can explain it?
Why would it be so 100% impossible for this woman to ask her dad for money, when she has probably had him wrapped around her finger since she was 1 years old (if not younger), and has always probably manipulated him for money, and he has probably showered her with material spoils - just because he doesn't like her husband, doesn't mean he doesn't want his daughter to be happy.
He would not deny money requests from his beloved daughter, especially if she explains that the family really needs the money. Jerry doesn't live or operate separately, as an individual entity and a loaner, any money Jerry gets, is eventually going to be shared with the wife, so there's no need for the grumpy old guy to deny Jerry money - women are VERY good at extracting their husband's money, and so on.
You can think of this from so many angles, and the end result is, the wife WILL and already SHOULD have a ton of money, the dad will provide her with money any time she wants it, and she's SO sweet, kind and even has 'that face' that would HAPPILY help Jerry - HER HUSBAND! - if he's in trouble, and do everything in her power (and believe me, she WOULD have power even over someone as gumpy as her father, EVEN IF he wasn't her father, but especially because he is!) to help him and get that money from her father.
There's just _NO_ way a wife like _THAT_ wouldn't a) be ABLE to get and b) be WILLING to get a ton of money for her beloved, hard-working husband with puppy eyes, no matter what kind of father she has, as long as that father is wealthy. And he is.
So this portion of the story and the movie, and how it's shown to us, is _NOT_BELIEVABLE_WHATSOEVER.
That makes it a major plot hole, maybe biggest in any movie.
