At work, Tom and Jack were chatting:
Tom: Jack, I've been attending evening classes for 8 months now and I have a test next month.
Tom: For example, do you know who is Thomas Edison?
Tom: He's the inventor of the light bulb; if you take evening classes you would know this.
The next day, the same discussion took place:
Tom: Do you know who Gandhi is?
Tom: He's the key architect of Indian Independence, if you take evening courses, you would know this.
The next day, once again:
Tom: And do you know who J.K Rowling is?
Tom: She's the author of Harry Potter series, if you take evening courses, you would know this.
This time, Jack got irritated and said: And you, do you know who is Kevin Johnny?
Jack: He's the guy roaming with your wife everyday!! If you stop evening courses, you would know.
Moral: There are some things more important in life than Work and General Knowledge
