I wasted more than an hour looking for it on YouTube, but I couldn't find it. It might have helped if I could remember the car company it was for.
'It' was a commercial I saw years ago for someone's SUV. It consisted of several families all over the world driving the thing in all climates.
The last clip was of an African family driving across the desert. The kids are fighting and dad is looking miserable. All this is in the native language, complete with clicks and glottal stops. Finally mom, who is driving, sternly says something in her glorious clickety-click speech.
The subtitle says "Don't make me come back there!"
Better if I could have shown it, but there it is.
