At the top of the image, "Jon, you're wheely old—but at least downhill biking is your age group's new cardio!"

- The image features a sunny hillside with Jon—depicted as a cheerful, slightly wild-eyed cartoon character in a birthday hat—zipping down a steep trail on a mountain bike.

- He's clinging to the handlebars with one hand, while the other is holding a melting slice of birthday cake on a paper plate.

- A group of cartoon squirrels cheer him on from the sidelines holding mini "Happy Birthday!" flags.

- One tree has a sign nailed to it reading, "Caution: Birthday Boy Approaching at Extreme Speeds!"

- Exaggerated motion lines, flying frosting, and flapping party streamers make the whole scene joyfully chaotic.
