This is too hard - there's no one character that annoys me consistently in Buffy - they all annoy me at times. Because the ones with the most screen time will have had the most opportunity to annoy me it means that, like Hazel, I'm going to have to pick Xander ... and mostly for the reasons she mentions. Ugh! Can't even be arsed to find a picture... sorry... I'm glad the favourite/least favourite character thing is done now... that was a bit of a yawn - hopefully the remaining 23 days will be more stimulating.
