A CMOF? in Diablo? Yes. Even the darkest of games will have the occasional laugh. (For funny moments in ''VideoGame/DiabloIII'', click [[Funny/DiabloIII here]].)

* The [[http://www.youtube.com/watch?v=qSlGQpvl_IA secret Cow Level]] is populated by 7 foot tall cows toting poleaxes, which is funny enough by itself. But the voice actors' bored "moo." for the patrolling enemies pushes it over the top.
* Some of the Necromancer's lines are quite funny in a DeadpanSnarker kind of way. Like after defeating the last boss of the optional fourth quest in Act 1, which yields a considerable amount of gold, he says:
--->'''Necromancer''': Treasure hunting? Hmph! Treasure finding? Yeeess.
** Also, his reaction after stopping SnakePeople who were trying to put eternal night over the country:
--->'''Necromancer''': A Shame. [[NightmareFetishist I was starting to enjoy darkness]].
* Lysander seems to be [[ICantHearYou a bit hard of hearing]]:
--->'''Lysander''': Horazon's [[AnachronismStew Urinal]]? Oh, journal! Yes, well... Glad you found it. Such a shame about those poor harem girls, huh? [[IReadItForTheArticles I shall miss them deeply... I mean their conversations, of course.]]
* If you find out what Diablo is [[SubliminalSeduction really saying]] the instant the final level starts...
--->'''Diablo''': [[CommanderKeen Eat your vegetables]] [[NightmareRetardant and brush after every meal.]]
* And of course in the first game's Hellfire expansion, through a certain exploit, you get to hear [[FinalBoss Na-Krul]] say this gem.
--->'''Na-Krul''': Hi! I'm free, free to confront the little man who banished me, Diablo. Hi, everybody, and I'm free to reward you, little mortal, with these Aerosmith tickets. You'll be getting backstage passes, you'll get to meet Steven Tyler and the whole band. This Friday at the Coliseum. Thanks for getting me out of there. By the way, I'm gonna have to kill you. [[{{Beat}} *pause*]] I'll be right back with the traffic and weather together.
* Gheed has a hilarious line if you try to talk to him before finishing The Forgotten Tower quest.
--->Guess what! I've named a boil on my ass after you. It, too, bothers me every time I sit down."
