Indira Gandhi wanted Zail Singh and Buta Singh to learn English. She sent them to the UK warning them that if they did not learn in 6 months she will have them shot.
In UK both forget about learning till the time to go back comes. Now when they return to India, the PM calls them for an interview. Zail Singh forces Buta to go in first. Indira Gandhi writes a big M on the blackboard. After scratching his beard Buta says ” M! M for mother.” He gets the nod from the PM and comes out beaming with pride. As usual Zail Singh pleads to tell what happened inside and Buta explains.
Now comes Zail Singhs turn. He goes in. There is a big W on the board. Zail Singh fidgets for some time and there cries out, “Lagdi to Bute di maa hai, par ulti tangi pai hai!”
