Humorous 40th birthday shirt with St. Louis joke—for Missouri natives turning 40 or celebrating someone who is.
The story behind this design
White tee, straightforward and clever: at the top, I'm Farty in bold white capitals. Below, smaller text delivers the local punchline: To most people, it means you have gas, but to St. Louisans, it refers to being 40 years old. The typography is clean and easy to read, the humor simple but effective. This is the kind of design that lands best if you grew up in or around St. Louis—it's an inside-joke shirt, the type you wear to a birthday party where everyone gets it and laughs. Funny without trying too hard.
Who it's for
Perfect for anyone turning 40 in or from St. Louis, or as a gift from friends and family who want to celebrate that milestone with local humor. Ideal for St. Louis natives living elsewhere who appreciate regional wordplay, reunion events, or casual birthday celebrations where the joke hits harder because of the inside connection.
