Sardar ji was suffering from episodes of terrible recurring headaches. So he went to a doctor and did all the tests. He was told to come after a week for the result and so he did.

Doctor: I am terribly sorry but you have a tumor in your brain...

Having heard the news, Sardar ji was all excited and started to dance. Tonaktunatun Tonaktunatun Tonaktunatun tanana....Aree balle balle...While he was cherishing, the doctor was standing next to him all surprised...

Doctor: Didn't you heard what I just told? You have a brain tumor.
Sardar ji: Oh I heard it alright.
Doctor: Then what is the purpose of this celebration?
Sardar ji: At least now I know I have a brain.
