Slack Wyrm is a fire-farting dragon. It's also the name of the continuing comic series by Joshua Wright (previously at Neatorama) that the dragon stars in. However, many of the comics can stand on their own, like this one. Never has a chicken held so much power in her hands! Er, wings.
If you want find out what happened after Janet's judgement, see the next comic. Afterward, Slack Wyrm turned a new leaf and is now on a quest with a wizard to find the kingdom's worst troll. Yeah, he's an internet troll. You can read the entire series starting here. -via Geeks Are Sexy
