8. Agnes
20th Century Fox TelevisionAgnes Skinner is a woman primarily characterised by strong contempt towards the human race but, more often than not, that contempt is directed at her son, Principal Seymour Skinner. Now, dont get it wrong, seeing Skinner abused is something that we can all enjoy time and time again. However, this is something best left up to the professionals: Bart, Chalmers or the mysterious El Barto. Agnes just comes off mean for no reason without actually being funny. Unlike most other entries on this list, Agnes was given plenty of scenes over the years she had various romances, most notably with Jeff Albertson (hardcore fans will know who that is), she was part of the Investorettes, she was on the curling team etc. She had plenty of stuff to work with but she still remains unlikable and thats unlikely to change in the future. She occasionally displays moments of affection for Skinner. When this happens, she becomes more likable as a character, but the humour dissapears. In order for her to become more popular, a balance needs to be found between the two.
