This Taylor Swift ‘Bad Blood’ lip-sync takes an unexpected, dark, PSA turn

Australian trio SketchShe have attracted so many millions of YouTube views purely from lip-syncing in a car, that it seems they felt duty bound to point out that it’s actually a very dangerous thing to do (at least with such zeal) on real roads.

Their latest video sees them enthusiastically lip-syncing and dancing to Taylor Swift’s 'Bad Blood', only to end up in a car accident during the chorus.

‘Don’t lip-sync and drive’ the video then warns after a fairly high production-value crash, as onlookers rush to the car.

If we're going to implore the public not to do things they see on YouTube, the girls might also consider:

'Don't talk for 38 minutes about a guitar pedal'

'Don't make mash-ups of Harry Potter romances that never were, set to Evanescence'

Don't 'Swegway dance' to Justin Bieber'
