Why Did Parvati Marry Shiva?

Teacher: Why did Parvati marry Shiva? 

Student: Shiva does not wear clothes so the washing is minimal. The moon in the head will always be light ... EB bill will not come .. !! Ganga River from Jatamudy River, do not load the motor with the tank .. !! Shiva eats green vegetables.. Shiva does not mother-in-law, father-in-law ... so no trouble from in-laws.

 The teacher, who was fed up and fainted with the student's response, never got up again.
