Logic - as simple as that!

Zailsingh decided to write the MBA exam. He understood everything except for the logic part. One day while reading, Rajiv came home.  And the following conversation took place.

Rajiv:               Zailsinghji - How is your MBA preparation?
Zail Singh:      Everything is fine, but I could not understand Logic.
Rajiv:               Logic is very easy.
Zailsingh:        Can you give me an example, so that I can understand.
Rajiv:               OK. Do you have fish pot in your house?
Zail:                 Yes.
Rajiv:               Logically, there will be water in it.
Zail:                 Yes.
Rajiv:               Logically, there will be fish in it.
Zail:                 Yes.
Rajiv:               Logically, someone will be feeding the fish.
Zail:                 Yes.
Rajiv:               I take a guess that your wife will be feeding the fish.
Zail:                 Yes.
Rajiv:               So, logically, you are married.
Zail:                 Yes.
Rajiv:               So, that means you are a heterosexual. 

Zailsingh was very glad that he understood logic. Next day he met Buta Singh who was also preparing for MBA. 

Zail:                 How is your MBA preparation?
Buta:               Everything is fine except for the logic part.
Zail:                 Oh, logic is easy.
Buta:               Could you please, give me an example. 

Zail:                 Why not - Do you have a fish pot in your house?
Buta:               No, I don't.
Zail:                 Saala* homo!!!
