It’s called a smash cut. It’s a film technique where one scene abruptly cuts to another scene without warning. It’s used to startle the audience, usually for comedic or dramatic effect. More on that on the commentary track.
You may also recognize the punchline from an episode of Futurama. It’s one of my favorite lines from that show and I just couldn’t help myself… (actually now that I write this, I am realizing that it comes from an episode with robots on a deserted island… Woah… I’m freaking out right now.)
EDIT: I sound so sick on todays commentary track. I apologize guys. Bleugh!
