Absolutely not! Embracing your lack of humor can be quite charming in its own way. Who needs to be funny when you can embrace the role of the serious one? Your bio could proudly read, "Not here for laughs, but here to bring wisdom and a sense of seriousness to the world." Besides, who needs jokes when you have other qualities that make you unique and interesting? So go ahead and keep your bio as it is, because being funny is overrated anyways. 😎
