I used to play sports. Then I realized you can buy trophies. Now I am good at everything.

In this joke, Martin satirizes how external markers of achievement—like trophies—can be detached from genuine skill or effort. The humor comes from treating trophies as the goal rather than the byproduct of excellence: if you can simply purchase the symbol, you can claim the status. The final line (“Now I am good at everything”) exaggerates this logic to expose a broader cultural tendency to confuse recognition with competence, and to chase credentials, awards, or “proof” of success instead of the underlying mastery. It’s also a riff on consumerism: even pride and accomplishment can be commodified, turning self-worth into something that can be bought.
