Surprised by some rapid posting, I decided to check 'Who's Online'. Living as I do in a timezone shared by very few others, and hence not used to the presence of others on the board cotemporaneously and at the same time, I commented to self "There are more users online that you can poke a stick at". This:

1) was the first sign of madness
b) was doubtfully true, depending on the size of the stick, and
iii) caused me to question the origin of the term "there are more ... that you can poke a stick at".

I have since decided that I am not mad, and I don't even have a stick, but I need some help with iii? Any takers?
