This is why I think Lloyd is missing a few marbles. He's not just *not* smart, he's actually dumb.
It's curious that the psychologist Andrew Gold interviewed (couldn't find the video on Andrew's page) about Lloyd mentioned he felt he was a psychopath (IIRC). The definition of a psychopath: a mentally unstable person especially: a person having an egocentric and antisocial personality marked by a lack of remorse for one's actions, an absence of empathy for others, and often criminal tendencies.
Psychopaths can be cunning while calm yet totally stupid when they feel insulted often acting instead of thinking.
