I'm not sure if it's a movie, or a YouTube video from years ago. If you recognize it let me know. (Some things are fuzzy)
Theres this adult but lazy dude living with his parents. He's on a bus of some sort, when the radio starts broadcasting that theres an apocalypse. He ends up waking up in a hospital with this girl and he protects her. They end up in this facility after looking for his family, theyve gone full survival mode with rasions. Then it's revealed to all be a prank, the zombies outside are actors, the little girl is actually an adult acting like a kid, he freaks out that it's all fake yada yada. The actual video is way longer than my explanation.I can't find it anywhere, so I'm beginning to think it's a youtube video but again this is from years ago, more than 4
