Today’s silly joke

This was passed to me…

A mechanical engineer, chemical engineer and software engineer are driving on a beautiful spring day. Suddenly, their car breaks down. The three engineers discuss how to fix the problem.

“It must be a mechanical fault,” says the mechanical engineer. “Let’s pop the hood and repair the engine.”

“No, there’s something wrong with the gasoline,” argues the chemical engineer. “We need to filter or replace the fuel.”

Both argue with each other, until the software engineer offers the solution: “Just close all the windows, and then open them again. That usually does the trick.”
