Tozan went to interview with the PI. The PI asked him what kind of project he had worked on.
Tozan said: `Total synthesis.'
The PI asked: `What target did you work towards?'
Tozan replied: `Jackoffamycin.'
`What step did you stop at?' asked the PI, wondering how long Tozan would continue with such factual answers.
`The twenty-fifth,' answered Tozan.
The PI said: `I should give you three blows with a stick, but today I forgive you.'
The next day Tozan bowed to the PI and asked: `Yesterday you forgave me three blows. I do not know why you thought me wrong.'
The PI, rebuking Tozan's spiritless responses, said: `You are good for nothing. You simply wander from one project to another.'
Before the PI’s words were ended Tozan was enlightened.
