Post a character who u can't stand and gets on your nerves

Excalibur (Soul Eater) is a character who now gets on my nerves and I can't stand. Especially when he says "Fool!", starts singing, and begins telling as well as recounting the days of his former lives just about EVERY single time whenever he appears/shows up in the series.

Also I swear I now feel like punching and kicking as well as even grabbing and using his very own cane to beat him up with it all the way into oblivion if I hear any plus stories of his past lives and his chant too just to make him SHUT UP
