You know that kid eating McDonalds green screen template? It is pure chaos. That little dude demolishing a Happy Meal with zero emotion is the perfect reaction to anything mildly inconvenient.
Use it when your friend says the Wi-Fi is down. Slap it behind a video of your boss dropping a new project on a Friday. The contrast between the mundane eating and the dramatic green screen background is what makes it hilarious.
It works best for relatable, first-world problem humor. Just put your clip in the background, keep the kid front and center, and let his deadpan munching do the comedy work. Simple, effective, and endlessly memeable.
