Netcat Listening At Port 80

The pun is strong with this one. Netcat (often abbreviated as 'nc') is a command-line utility used to read and write data across network connections. Port 80 is the standard port for HTTP web traffic. So what we have here is the literal interpretation: actual cats inside a computer case "listening" at port 80. The kind of joke that makes network administrators silently exhale through their nose while maintaining that thousand-yard stare developed after years of troubleshooting DNS issues.
