Logic.
An annoying person would probably be able to formulate their motivations, since their ability to think complex thoughts would not be majorly impaired. You may expect, however, a stupid person to not know their motivations since their ability to think complex thoughts may be impaired.
Frink was probably trying to be all nice about it and beat around the bush and just give a nonsensical excuse. I don’t like beating around the bush. Just say it.
