Good start! I think Nigel is maybe slightly ahead at this stage.
Kitty, you gave me an idea...

How many times can a man go astray, when working here at the bank,
How many pin numbers must you send out, for which you will not get a thank,
How many times can you ring the help-line, before you finally go blind,
The answer, my friend, is blowing in the wind,
The answer is blowing in the wind.
