Joke: The Dad who does not Understand English

A boy was with his father when he saw his girlfriend coming. 

BOY: Have you come to collect your book titled; "SPEAK ENGLISH MY DAD DOESN'T UNDERSTAND IT?" by Ngozi Okafor. 

Girl: No, I want that our hymns called "WHERE SHOULD I WAIT FOR YOU?" 
Boy: I don't have that one... may be you should take the other one "UNDER THE MANGO TREE" by Crooks.

Girl: Fine but don't forget to bring "I WILL CALL YOU IN 5 MINS" while coming to school... 

Boy: I will also bring this one too, "I WON'T LET YOU DOWN" by Chinua Achebe. 

Then; 

Dad: These are too many, will she read all of them?

Boy: Yes dad, she is very smart.

Dad: Okay, don't forget to give her the one on the table titled, "I AM NOT STUPID, I UNDERSTOOD EVERYTHING YOU'VE BEEN SAYING" by Shakespeare!
