No matter what the average level of intellect and social skills are, no matter how many people are in a group, no matter what the age of those people is, there will always be at least one person who is a total idiot.

IRC is a good bit of proof for this...

I don't know if I can wait this long
To be what I used to be
And I don't think I can wait much longer
For the tide to come back to me
Come back to me
