This funny scene is from an indian action-comedie movie called "Judwaa 2". Twin brothers Raja and Prem have a deep connection with each other and their reflexes operate simultaneously. That's why Raja feels the same pain suffered by Prem when his brother's balls are sqeezed by a bully. Too bad the bully doesn't know: he'd surely relish the idea of crushing two pair of nuts with one single move! :)
Anyway, what I like the most about this scene is the bully's smile as he grabs Prem. He's surely enjoying owning the poor guy.
