Dullard

Basically a Fukwit, who is trained to read a script but doesn't have a clue what it means.
Is trained to fill in the blanks or input three basic entries of information to get an answer then makes out he/she is the "Lord of All Information and shall not be passed"

Dullard: 'The computer says that that will be 'x' amount available.'

You: 'But you started your conversation with'y' amount.'
Dullard: 'Yes, but the answer is 'x'
You: 'How ?'
Dullard: 'Because that's what it tells me'
