But he pays it anyways.

The plumber tells him, “Hey, we are looking for more plumbers. You could become a plumber and triple your salary. Just make sure you say you only made it to 6th grade, they don’t like educated people.”

The professor takes him up on the offer and becomes a plumber.

His salary triples and he doesn’t have to work nearly as hard.

But the company makes an announcement that all of their plumbers must get a 7th grade education.

So they all go to night school.

On the first day of night school they all attend math class.

The teacher wants to gauge the class so he asks John, “What is the formula for the area of a circle?”

John walks up to the board and is about to write the formula when he realizes he has forgotten it.

So he begins to attempt to derive the formula, filling the board with complicated mathematics.

He ends up figuring out it is negative pi times radius squared.

Everyone finished in 2 minutes, and they all went to break.

When they came back, the teacher was furious.

It turned out they had all written ‘3141592653’.

All the digits were correct of course, but the decimal point was missing.
