At Kenna, we have a module called Mr. Radar. We use it to run two cron jobs, one nightly and one every 30 min. Each job looks for anomalies in data that might indicate a problem and alerts us if it finds any.
We were demo'ing the tool to our Sales team one day and they listened very intently for an hour. At the very end, one guy's eyes lit up and he asked "Is that a Spaceballs reference?!" The entire team lost it laughing and replied, "YEP!"
What is the most creative module or class name you have seen? It could be in your own code base or it could be in an open source code base!
