naam do do rakhe huye hain, kaam ek bhii naheen aataa

Film : The Dirty Picture

Year of release : 2011

Spoken by : Suryakant (Naseeruddin Shah)

Spoken to : Reshma (Vidya Balan)

Dialogue writer : Rajat Aroraa

While her debut shot with Superstar Surya is being shot, Reshma aka Silk repeatedly messes up her steps. Surya gets irritated and asks for a solo shot to be set up. Then he beckons Silk:

"e ladkii...idhar aa...kyaa naam hai tera?"

"Reshmaa ...er...Silk"

With a derisive chuckle, Surya says, 

"naam do do rakhe huye hain, kaam ek bhii naheen aataa!"

"नाम दो दो रक्खे हुए हैं, काम एक भी नहीं आता!"

A great line to use with people who have two names (like Arun Prakash or Shekhar Suman, or even with those who have a regular name and a pet name or Daak naam as the Bengalis call it). Use it when they mess up.
