Willam is referred to as an "idiot man-child" by other characters in the View Askewniverse. His limited intelligence and demeanor (glazed eyes, unkempt hair and beard, and lack of coordination) lend credence to this title. Despite his intellectual limitations, he can be very determined at times, as his quest to see a hidden sailboat in a Magic Eye picture demonstrates. Willam also has an oddly profane sexual taste, which includes snowballing, thus giving him his other nickname, "Snowball".
