Gas station attendant
An enlightened person who knows everything but has nothing better to do with their live. They never tell anyone because they would think they where lying or insane.
Next time you go and get gas ask the gas station attendant a question they tell you either:
1) that they don't know - but they actually do or
2) an answer in which you don't know weather they are lying or not
