McGucket is the local kook, and is, as the title implies, mildly senile. However, it is shown that he is quite intelligent, and has the ability to create giant mechanical contraptions. This plays into his insanity, as he uses them for things like getting attention from his son, revenge against an old colleague for not coming to his retirement party, etc. He can seem to be a bit depressed at times, but this is only for brief moments. Instead, he's usually optimistic and occasionally even helps.
