Talking of fast things:
Three blokes applied for a job. After the interview they couldn't be split.
The interviewer decided to call the three back in and ask them only one question. Their answer would determine which of them would get the job.
As the three interviewees sat around the conference room table, the interviewer asked, 'What is the fastest thing you know of?'
The first man replied, 'A THOUGHT.' It just pops into your head. There's no warning. One minute it's not there, then boom, you think about something.
'That's very good!' replied the interviewer. 'And, now you?', he asked the second man.
'Well, at my dad's farm, when you step out of the house, there's a light switch on the wall. When you flip the switch, way out across the field the light in the barn comes on in an instant. 'Yep, TURNING ON A LIGHT is the fastest thing I can think of'.
The interviewer was even more impressed with the second answer and thought he had found his man.
Turning to the third and final man, the interviewer said, 'It's going to be hard to beat the speed of light mate,' but.give it your best shot.
He replied, 'Well, after hearing the previous two answers, it's obvious to me that the fastest thing known is DIAHORRHEA.'
'WHAT!?' said the interviewer, stunned by the response.
'Yep', he says. 'I woke up with a bout the other night and before I could even think about switching the light on I'd shit myself.'
