We’re shown various areas of a house, where strange fingerprints are present on all the household items, as we hear a phone ringing in the background. First, an electric toothbrush, a light switch, a glass of water, and finally a cell phone with a broken screen. We then see Bill Hader sitting on the couch staring at his phone. All of his fingers are bandaged, and it seems that Bill Hader is extremely hesitant to answer his phone. He looks at his bloody fingers and then builds up the courage to answer the phone. He goes to swipe the screen to answer the phone, and cuts his finger again on the broken screen. And now we know, that all the bloody fingerprints found around the house are from Bill Hader cutting his fingers multiple times on his old broken cell phone screen.
