WTF?

An older man with white hair, wearing a light-colored collared shirt, stands outdoors next to a woman with blonde hair, both in front of a house with green trees in the background; the man turns his head and opens his mouth wide in a loud yell or laugh, his face blurred by motion, while the woman smiles; the scene then cuts to the man's face superimposed onto the Metro Goldwyn Mayer lion logo, where his head moves slightly as if roaring, with the text "Metro Goldwyn Mayer" and "Vine by Matt Smith" visible.
