The John Mulaney not funny green screen template is a classic bit of internet irony. It takes a clip of the comedian looking deadpan or awkward, usually paired with text claiming he isn't funny. The joke is that it's obviously funny because you're using a clip of a famous comedian.
This template works best for moments when someone tries to be edgy or controversial but fails miserably. You can use it to react to bad takes, cringe jokes, or when someone says something that just completely misses the mark. The green screen lets you insert any background, making it perfect for reacting to other videos or memes.
The humor comes from the contrast between Mulaney's serious face and the absurdity of the situation. It's a self-aware way to call something unfunny without being mean. Just drop the clip into your editing software and layer your own context on top.
