Does anybody here remember seeing a movie with the following scene?

A truck pushes a Porsche through the window of a house or something, and goes on to smash its way through it (the house is packed with people). By the end, cows start walking out of the wreckage. (Don't ask why, I'm not sure of the context.)

I saw this scene in an episode of The Fall Guy (season 2 episode 14, "Death Boat" to be precise), and while I can't confirm it, it really looks like stock footage, and I tried to find the movie it came from. But I can't.

So... could anyone identify the movie it came from (if there is)?
