No, it's not some glitzy song or dance number, it's this short and poignant scene from "Dancer". Akshay's mom has just been released from prison for a crime she didn't commit (of course), so they are reunited for the first time in probably 15 years. He lays his head in her lap and she massages his scalp while he falls asleep. She continues to massage him even after a scorpion comes up and bites her several times on the toe. For several more hours, in fact. When Akshay finally wakes up and sees all the blood on the floor, she just says something like, "Oh, it's nothing". Now there is true devotion!
On the other hand, if I were Akshay's mother, or brother, or cousin, or the postman, or a stranger from off the street, I might be inclined to do exactly the same thing. It's not every day you're going to get to hold Akshay's head in your lap.
I have used this scene as an example to workmates when they have been complaining. I say, "In India, a mother will bite her lip and bear the sting of a scorpion, rather than wake her son from his sleep". I haven't tried that one on my mom yet, though.
