Which episode?

Some director or something, I know it wasn't an actor, but he was talking about a movie where someone's family had come to visit and when they left a plane crashed into their car, or their plane crashed into a car. I don't remember and I don't have time to go through it all again. But I remember he said something about it being a horror movie so you remember the bad stuff that happened, and if you do a comedy you remember the funny stuff that happens.
