Do You Know Who Is?

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.

Jack: oh!

Tom: For example, do you know who is Thomas Edison?

Jack: No

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?

Jack: No

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?

Jack: No

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?

Tom: No

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
