Description Harold has known Angelica and Susie since pre-school and reminds them of that fact every chance he gets. He is good natured and means well, but Harold can tend to be a bit annoying, to say the least. His social skills have a lot to be desired, and he often matches Phil in terms of grossness, although most of the time he is oblivious as to how gross he is. Despite her constant put-downs, Harold dotes on Angelica, and he may be the only guy out there who worships her the way she wishes everyone would. - All Grown Up! Description from Klasky Csupo.
