I couldn't understand why I was even assigned such a ridiculous quest as to find the body parts of some clown, famous or not. Of course I didn't bother completing it.
I know there's a place for humour and such, but on what grounds would a 12th level character who has defeated an avatar of death, and is on a quest to save themselves, their companions and Baldur's Gate, take on such a quest??
It breaks the 4th wall simply to present the completionist with something extra to do.
Eh I think you're taking it a bit too seriously. Even in BG2, Throne of Bhaal, when your characters were epic-level and basically walking demigods, there were still some silly quests along the way.
