A project manager, a computer
programmer and a computer operator are driving down the road when the
car they are in gets a flat tyre. The three men try to solve the
problem. The project manager said: "Let's catch a cab and in ten
minutes we'll reach our destination. " The computer programmer said:
"We have here the driver's guide. I can easily replace the flat tyre
and continue our drive." The computer operator said: "First of all, let's turn off the engine and turn it on again. Maybe it will fix the problem." Suddenly
a Microsoft software engineer passed by and said: "Try to close all
windows, get off the car, and then get in and try again."
