Through both work and personal preference I've seen a lot of Bollywood in my time. Combining dance AND a capella singing? Coming from someone who can barely chew gum and walk at the same time, that's just pro.
When I first played this, I thought, "ho-hum, another surprise dance video." But the sheer explicitness (contains multiple f-bombs!) of this couple's movie homage soundtrack choice made me cringe. I wonder if their own respective mothers were expecting the line, "Imma execute every mothaf**king last one of you!" In their children's day of holy matrimony?
