It's A Perplexing Life

I've been watching It's A Wonderful Life about 1000 times lately and,even though I have seen it a few hundred times already, I've just noticed a few things about the movie that make no sense at all!  

1). When Uncle Billy is in the bank...
In this scene, we see Uncle Billy counting $8000.00 and filling out a deposit slip when he runs into Mr. Potter.  He has a newspaper in his hands that display the headline praising his nephew, Harry, for being a war hero. He walks up to Potter, gloating about his nephews accomplishments and then accidentally puts the $8000.00 inside the newspaper and gives the newspaper to Mr. Potter.  He goes to the teller to deposit the money but realizes he no longer has it.  
Making no sense at all, Uncle Billy then returns to the building and loan looking for the money and, when he can't find it there, he supposedly tears his house apart in an attempt to locate the missing money.  How does he not remember that he had counted the money at the bank and therefore, it cannot possibly be at the office or at home but somewhere at the bank.  

2). The kids had school on Christmas Eve day???...
According to the story line, Zuzu won a flower at school that day...and that day was Christmas Eve day. 

3). Zuzu catches a cold walking home from school...
Again, according to the story line, Zuzu won a flower at school that day and caught a cold because she walked home without zipping her jacket so that she wouldn't ruin the flower.  First of all, one cannot catch a cold that way.  But what really does not make sense is how fast she catches said cold.  We are supposed to believe that she left school completely healthy and arrived home minutes later with a cold because she did not zip up her coat???  Ummmm...nope. 

4). How does the teacher even know that Zuzu is sick???...
While George is home, the teacher (Mrs. Welsh) calls to check on Zuzu.  Since we are supposed to postulate that Zuzu got sick on her walk home from school, how is the teacher even aware that she is unwell?

4).  Mr. Welsh just happens to be at the same bar as George...on Christmas Eve...
Prior to the scene at the bar, George gets on the phone with the teacher and vituperates her for letting Zuzu walk home without her coat zipped up (and incidentally, the teacher could not have knowledge of the coat debacle unless she was walking home with them!). Naturally, the teacher becomes upset, prompting her husband to get on the line and threaten to harm George for treating his wife that way.  
Later on, after George gives his family a verbal tongue-lashing, he leaves home and goes to the local bar.  There, in an inconceivable coincidence,  he runs into the teacher's husband, Mr. Welsh, who then punches George in the face.  

5).  Your mouth's bleeding, George...
After getting punched by Mr. Wells, George's lip is bleeding.  He leaves the bar, drives drunk, and crashes into a tree.  He then gets out of the car and walks to a bridge where he is contemplating jumping into the water to commit suicide. Here, he meets his guardian angel who jumps into the water himself, forcing George to save him.  
After a sequence of events that gives George a look of what life would be like had he not been born, he returns to the bridge and begs to "live again."  Here, enters the policeman who exclaims "you okay George, your mouth is bleeding."  Really?  The jump in the water did not clean the blood off his lip?  

Despite these dubious scenes, the movie is great and one of my favorites.
