Teachers' Day Special

Although I admire all my teachers and I love my job of economics professor,
there are times I feel like this:
(A.S. - it would sound good if you know the tune of the original song of this parody)

Bhaiyya hum to hain professor
be-sir-pair ka ek lecture
classes bhi.... fundae maaro to chalen

economics ki aisi ghutti,
paisa, fursat, aur chhutti,
teeno_n hi.... fundae pelo to milen

ye classroom tension hai, students maali hain............
chakkar me acads ke life ka ho gaya poora-poora foam... foam... foam.... om!!!
om om hari-om hari-om hari-om om om hari-om hari om.....
