Gautam Gundiah told me this joke while I was at IISc, and I have slightly modified it:
 

Asha Parekh dies and her soul is on the way to heaven, but suddenly she starts moving towards hell. So she asks Chitragupta, "Yeh kya ho raha hai? Yeh kya kar rahey ho? Mujhe narak mein kyon bhej rahey ho, maine to kuch paap nahin kiye hain" ... Chitragupta looks in his ledger and says "Tumne khud itne saare picture mein heroine bankar sensuous dances kiye (He grimaces at this point), phir Censor Board mein doosre logon ko picture entirety mein release karne se roka hai, yeh paap hai, aur tum jaise logon ko narak mein hi hona chahiye." To which Asha says, "Lekin Bhagwan se poocho! Yeh paap nahin hai! Mujhe Bhagwan se baat karne do!" Chitragupta shrugs and says, "Bhagwan antaryaami hain, unhein sab kuch pata hai! Aur woh tum jaise logon ke liye samay barbaad nahin kar sakte hain, parantu agar tum chahti ho to pooch lo unhi se" and the next thing you know, she's standing in front of the stairs leading to God's throne. She looks up, and says, "Bhagwan?" and God replies, "Bolo, kya baat hai?" She says, "Bhagwan, meri ek choti si aas hai" God says, "Chal, jhoothi!"

The moral of the story is - Asha Parekh never had an hourglass figure. She was butt-ugly when she was in the movies, and she's uglier now that she's trying to stop other people from having a little fun with their movies (alright, I don't mean it that way but you get the point. I hate her.) What does it mean when you are in movies one day, in songs with the "skin dress" on as if you're exposing your privates, and the next day you are being such a fucking prude?!

I think it is best summarized by the first line of the song from the Manoj Kumar - Asha Parekh starrer, Saajan:  "Parde mein rehne do, parda na uthao" What she means to say in the song is, she's so fucking ugly that you BETTER not lift the purdah.
