Write me a short story about a duck who is going to law school. make it for children, make it have a happy ending. make it from the perspective of the duck's teacher. 
I've been teaching this class for nearly a decade, and never have I seen something so bizarre. A duck came into my classroom as a student! I originally tried to call security, but they didn't help at all. They just told me the duck was a student named Duckiffer Duckinson. As a teacher, I can't just send a student away, but it's a duck. I can't teach a duck. Well, whatever, there's no way a duck can successfully pass my class.

It's the end of the semester. I am still in shock. This duck is the best writer/law student I have ever seen. He always submits papers on time, he always goes to my extra help lessons, and this duck has never been late to my class even once! I don't think he even got sick this semester! Not to mention he has written the best papers I have ever seen and is the first student ever to receive a 100% in my class. 

At first, I was suspicious of the duck, but then I saw it take notes. It has someone carry around a computer for it, and it can type on the computer with its beak, one key at a time. He communicates through the computer and has never spoken, so I think it's just the smartest duck in the world. Over the semester, I have grown to like this duck a lot. I have written a recommendation letter for him that will help him land any job he wants. I know he will be the best lawyer the world has ever seen.
