Take Jab Jab Phool Khile remake it 4 years later with the same set of people (add Rajendra Nath), tone down some of the female oppression, improve the heroine's dress-sense and you have Raja Saab.
Raju (Shashi Kapoor) is a young orphan at an orphanage who is much given to daydreaming and weird hairdos. His daydreams always involve him playing a king - Raja or Sheikh are both acceptable. In the grip of one such daydream he insults the visiting Princess Beautiful (Nanda) and is thrown out of the orphanage.
Poor Raju (violins, please) tries various jobs with indifferent success and finally lands up being a masseur to a real, live prince (Rajendra Nath). The said prince's oddities leave him unfazed and he is ecstatic to be near a real Raja.
Well, Prince Funny Singh has a problem. He needs to insult Princess Insolent and what better way to do so than to have her insulted by a fake Prince! So Raju is turned into Raja Saab - Prince Funny Singh himself - and the prince becomes his secretary. The two of them sail forth to Kashmir. (Yes readers, you are right. They fly to Kashmir but "sail forth" sounds much better and I am allowed a writer's license.)
Raju is coached thoroughly on the etiquette of princely insults but fails to deliver when faced with Princess Insolent. She is none other than the Princess Beautiful whom Raju had insulted but now loves. Prince F. Singh is at a loss to understand his protege's behaviour and worries about his miscarried plan when he has a stroke of good luck. Somebody serves Raju some champagne. Our poor, innocent, orphan (cue - violins) is drunk within no time and manages to insult Princess Beautiful to Prince Funny Singh's complete satisfaction.
The next day poor Raju wakes up without a trace of a hangover, but a very guilty conscience for having insulted his lady-love. When the source of this guilt is explained to Prince Funny Singh, he is touched. Even Princes are human and respect true love. He helps Raju win back the princess's forgiveness and two are soon in love, inspite of Raju's regrettable habit of speaking like Raj Kapoor's tramp.
The path of true love never runs smooth. The Princess's uncle is expected to join them any moment and he knows the true prince. The truth will come out. Raju decides to cut his losses and run. When the truth is revealed to the princess she is heartbroken and misses her Raja Saab terribly. A sad song later she decides to take action. She loiters around neighborhoods in Raju's native Bombay (aye, amchi Mumbai) with her maid (Shammi) and manages to locate him. Now comes the difficult part - how to convince him that she is willing to give up EVERYTHING to be with him? Simple - she cons him into believing that she was a fake princess like he was a fake prince. Brilliant! First he cons and then she cons and then the story becomes convoluted (pun intended).
Several twists later the story comes to an end. Raju and the princess are united in a happily-ever-after union with minimal female oppression (well, you cant have a masala movie with no female oppression - it comes with the territory).

Reasons to watch the movie:
1. The changing shades of Nanda's eyes.
2. Rajendra Nath's weight-lifting bouts.
3. Nice songs - Kal raat waali mulaqat, Humne aaj se tumhen, Tu jungle ki morni, Raju ka hai ek khwaab.
4. The ever beautiful Kashmir.
Reasons to avoid the movie:
1. Lame story
2. Shashi channels big brother Raj - very annoying!
