Well yes, they are, but I bet your MMO hasn't asked you to literally crawl up a giant's rectum and clean out his bowel (yet). In Heart of Fire, this isn't just a quest, it's one that's repeatable once a week.
Yeah, I'm not quite sure what to make of the humour in this module. I was never really a fan of the Penny Arcade comic... every now and then someone would link me a particular strip about MMO mechanics or something and I'd go "heh yeah, that's pretty spot on" but if I tried to browse the archives at all I'd quickly get bored as I didn't find most of them even mildly amusing.
The new storyline in Heart of Fire is at least kind of funny so far; it's just all incredibly over the top, with characters constantly spouting anachronistic dialogue or the story centering on juvenile jokes like the quest mentioned above. It's all just a little bit jarring when compared to the rest of the game.
