Nice one

A Paki, Bangladeshi and Banta Singh are in a bar one night having a beer.

The Paki drinks his beer and suddenly throws his glass in the air, pulls out a gun and shoots the glass to pieces.

He says "In Islamabad our glasses are so cheap that we don't need to drink from the same one twice."

The Bangladeshi [obviously impressed by this] drinks his beer, throws his glass into the air, pulls
out his gun and shoots the glass to pieces. He says "In Dhaka we have so much sand to make the glasses
that we don't need to drink out of the same glass twice either."

Banta, cool as a cucumber, picks up his beer and drinks it, throws his glass into the air, pulls
out his gun and shoots the Paki and Bangladeshi. He says "In Delhi we have so many Paki and Bangladeshi guys
that we don't need to drink with the same ones twice.”
