A Paki, Bangladeshi and a Sardar

 
A Paki, Bangladeshi and a Sardar 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."

The Sardar , 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 Pakis and Bangladeshi that we don't need to drink with the same ones twice."
