Puff, the Magic Dragon

The Incompatible Timesharing System (ITS) is super weird in a lovable way. Did you know that Puff, the Magic Dragon lives in ITS? It's like a syslog daemon but in the ITS vocabulary, the idea of a "daemon" is instead called a "dragon" so of course they'd put Puff in there. This is before operating systems got all boring and "professional" and whatnot.
