that's not really a great sample size

No. It's not.

not of any statistical use whatsoever really

Unless you are presenting the case to morons.

ah, very good point.

Indeed. Morons tend not to care about the actual validity of the statistics, as long as there are statistics.

they don't usually even require that.

But it often helps, even if the statistics are useless or false.

most people who i've told '50% of all information is wrong' have either felt enlightened by that information or been sceptical that it was just made up but it's very rare that they've actually got the joke.

Ha! That is probably because 93% of people think that having a percentage in a statement makes the statement more likely to be serious.

I didn't know that, that would explain it.

It would explain it, were it not a joke in itself. It is probably somewhere close to the truth, which is where part of its humour comes from.

i thought my straight response was funnier

It was.

on the other hand it was quite lazy
