paco posted a single question and was never seen again. Sometime after that, Ovid started a campaign to make paco a Saint by trying to get every monk to vote for paco. It's succeeding quite nicely, given that paco has only one node to vote on. (It is the second highest-ranked node of all time.)

Update: I'll happily stand corrected. Erudil's node is the singularly most-recognized piece of Perl code.
