Well, there was this character in our Call of Cthulhu RPG. He was a very superstitious fisherman. When we entered an old lighthouse, he saw a black cat. He started freaking out, thinking it was a bad omen. He tried to chase the cat away but ended up falling down the stairs. We all burst out laughing. His over - the - top reaction to such a simple thing was just too funny in the context of the game.
I heard a story where a player's character, a journalist, was interviewing a cult leader. The journalist got so nervous that he started stuttering and asking really dumb questions. The cult leader was getting more and more confused and annoyed. Eventually, the journalist accidentally called the cult leader 'mom' and that was the end of the interview. It was a really funny moment.
One funny Call of Cthulhu story could be about a group of investigators who mistake a particularly fat and lazy cat for a minor Outer God's manifestation. They spend hours trying to decipher its 'enigmatic meows' and following it around the neighborhood, only to realize it was just a cat looking for food.
Unexpected twists can make a Call of Cthulhu story funny. For example, when the terrifying entity turns out to be something completely harmless like a group of squirrels that were misinterpreted due to some strange magical effect.
Well, there was this time when a Call of Cthulhu player's character was supposed to be stealthily observing a cult meeting. But he tripped over a pebble and tumbled right into the middle of the cultists. Instead of being sacrificed or something terrifying, the cultists were so shocked that they all ran away, thinking it was some kind of divine sign to scatter. The poor character was left there, confused but alive.
There was a Call of Cthulhu scenario where the investigators entered a strange underground lair. One of the investigators, who was always overly cautious, brought a whole suitcase full of 'protective items'. When they encountered a small, harmless rat, he panicked and started throwing everything from his suitcase at it. Holy water, crosses, and garlic were flying everywhere. His over - the - top reaction to such a minor threat was extremely funny to the others in the group.
There's a story about a Call of Cthulhu character who was trying to communicate with an otherworldly entity. He set up all these elaborate rituals and incantations. But when he finally made 'contact', it turned out to be his neighbor's cat that had wandered into his yard. The cat just meowed at him and he thought it was a sign from the Great Old Ones. It was quite a comical misunderstanding.
The common themes include cosmic horror, the insignificance of humanity in the face of vast and incomprehensible cosmic entities like Cthulhu. There is also a sense of madness that often befalls those who discover the truth about these otherworldly beings.
