"How Does This Train Run?" joke

A BIHARI was travelling by train for the first time. He was surprised to see the train running so fast. To gain a better understanding of how this was possible, he turned to his fellow
passenger who was a Sardarji.

Bihari:' Ee railgaadi kaise chalat hai?' (How does
this train run?)

Sardarji:' Iske neechey badey-badey chakke hain.'
(Under it there are large wheels.)

Bihari:' Uske neechey ka hai?' (What is under
that?)

Sardarji:' Uske neechey patri hai.' (The tracks
are under that.)

Bihari:' Uske neechey?' (Under that?)

Sardarji:' Kankar-pathar.' (Stones and pebbles.)

Bihari:' Uske neechey?' (Under that?)

Sardarji (getting annoyed):' Dharti hai.' (The
earth.)

Bihari:' Uske neechey?' (Under that?)

Sardarji (getting furious):' Uske neechey Pataal.'
(The underworld is under that.)

Bihari:' Uske neechey?' (Under that?)

Sardarji:' Uske neechey Mera Baap! (Under that,
My Father!)

Bihari:' Uske neechey?' (Under him?)
