I can always get better. A lot of my ex-girlfriends don’t think I’m funny.

The line pairs self-improvement rhetoric with a self-deprecating punchline. Cook frames “getting better” not as abstract artistic growth but as something tested in real relationships—where humor can fail to charm, or where former partners may revise their view of him after a breakup. The joke also undercuts the ego often associated with celebrity comics: instead of claiming universal appeal, he admits a specific audience segment (exes) is unimpressed. As a comic persona move, it signals humility while still reaffirming his identity as a comedian—someone who measures life through laughs, even when the laugh is on himself.
