Who is the villager who irritates you the most? What is it that they do that is so annoying?

Mine is a gent called Ayu whom I've lovingly nicknamed "The Fonze" because he looks like the Fonze, hates working, is in with all the ladies, and his sound is "Eh!" He annoys me because he never works and because every kid in the village must be his, all he ever does is "go indoors".
