Description: Ever wondered if you've seen every single quip that displays on the top of the pages on this site? I was curious, so I put together a little screen-scraper to check. Hey, it was a slow Sunday afternoon!

No command-line arguments for this script, but there are three variables at the top of the code (clearly marked) that provide some crude configuration. $iterations determines how often perlmonks.org is queried, $nice sets how long to pause between HTTP requests, while $status_print_interval configures how often the script pipes up with a quick status report to show it's still alive.

After 100 iterations, I think I've "collected 'em all", but I look forward to running this script every couple of months to see what other witticisms those [id://pmdev]s come up with:
********** RESULTS **********
2 time(s): Perl Sensitive Sunglasses
7 time(s): more useful options
9 time(s): Pathologically Eclectic Rubbish Lister
3 time(s): XP is just a number
8 time(s): Welcome to the Monastery
5 time(s): Think about Loose Coupling
3 time(s): P is for Practical
4 time(s): Syntactic Confectionary Delight
4 time(s): Perl Monk, Perl Meditation.
7 time(s): Your skill will accomplish what the force of many cannot
8 time(s): "be consistent."
5 time(s): go ahead... be a heretic
8 time(s): Keep It Simple, Stupid
6 time(s): laziness, impatience, and hubris
4 time(s): Perl: the Markov chain saw
10 time(s): There's more than one way to do things.
3 time(s): Just another Perl shrine
4 time(s): good chemistry is complicated,and a little bit messy-LW 
#!/usr/bin/perl
