Logical Song.....

Kyon Chalti Hai Pawan
Because Of Evaporation

Kyon Jhoome Hai Gagan
Because Of Earth's Revolution

Kyon Machalta Hai Mann
Because Of Excessive Respiration

Na Tum Jaano Na Hum
But I Just Gave All The Reasons!
Kyon Aati Hai Bahaar
Because Of A Change In Season

Kyon Lutata Hai Karaar
Because Of Mental Tension

Kyon Hota Hai Pyaar
Because Of Opposite Attraction
Na Tum Jaano Na Hum
Like I Said These Are All Scientific Phenomenon!
Kyon Gum Hai Har Disha
Because You Have A Poor Sense Of Direction

Kyon Hota Hai Nasha
Because Of Drug Addiction

kyon Aata Hai Mazaa

Because Physical Chemistry Gives Us All The Information
Na Tum Jaano Na Hum
I Did My Best To Explain
