A video of a model sashaying down a runway has gone viral for its gobsmacking ending.

American model Erica L. Carrington had the runway walk of her life to complete recently, but as she teeters her way down a long hallway and negotiates a set of steps as onlookers applaud, it seems that the 'fashion show' is not what you think it is.

And if you guessed what's revealed in the final few seconds, well, you either have a very strange sense of humour or a psychic gift.

Yes, that is a coffin and yes, this is a funeral service - although context is everything in this case.

It turns out that it is the funeral of fashion designer Vernest Moore at the Newark Museum of Art that has gone viral, although it's believed that the 'show' was in accordance with Moore's final wishes.

Model Erica Carrington, meanwhile, posted an explanation on her own Instagram page, calling it "one of THEE MOST CHALLENGING things I have had to do."
