What eccentric behavior makes Wendall Waxmo a wacko?

Wendall Waxmo is characterized as eccentric primarily due to his choice to wear a tuxedo to school. This behavior stands out because a tuxedo is typically associated with formal events, celebrations, or special occasions, and wearing it on a regular school day demonstrates a significant deviation from the norm of typical school attire. This choice can be seen as an expression of his unique personality, making it a notable eccentricity.

In contrast, running all the time, telling jokes during class, or never assigning homework might be seen as unconventional behaviors but do not carry the same strong visual impact or societal implications as wearing a tuxedo in a setting where casual clothing is expected. The tuxedo not only highlights his individuality but also could suggest a playful or whimsical approach to life, further contributing to the perception of him as a "wacko."
