Comic books are full of funny character names. For example, 'Deadpool' is a very humorous name. You can also look at different languages' translations of common words. In some languages, 'cat' might be translated in a really funny way and you could use that for a cat - like character in your story. Everyday objects around you can be a source. If you have a broken chair, you could name a character 'Wobbly - Chair Charlie'. And don't overlook the power of making up completely new words that just sound funny when you say them out loud, like 'Zippity - Zappity - Zack' for a really energetic character.
You can use puns. For example, if your story is about a clumsy detective, you could name him 'Sherlock Stumble'. Or combine two random words like 'Bubblegum Ninja'. Another way is to play with alliteration, such as 'Peter the Prankster' or 'Silly Sally'. You can also take inspiration from things around you, like if you see a funny - looking object, name a character after it, say 'The Lamp - Legs Larry' if there's a character with long, lanky legs.
How about 'Sir Gigglepants'? It gives the image of a jolly, perhaps slightly silly knight. Another could be 'Miss Fuzzlebubble', which sounds like a very whimsical and fun female character. And 'Professor Noodlehead' for a comical, absent - minded academic type.
One funny name could be 'Squawky the Eagle'. Another might be 'Flappy McEagle'. And there could also be 'Goofy Wingspan' as a humorous name for an eagle in a story.
Some great funny names for private stories could be 'The Exclusive Escapades'. This name makes it seem like the story is something only a select few can know about and is full of adventures that are also quite humorous. 'The Clandestine Comedy' is another good choice. It clearly states that it's a comedy but also something that is hidden or private. You could also go for 'The Hushed-up Humor' which gives the sense that the humor in the story is something that is not widely known or shared, but rather kept quiet and private.
You can use names like 'Bubbles McGee'. It has a fun and light - hearted sound that can bring a comical element to a story. Another one could be 'Wacky Wally'. It gives the impression of a character who is a bit zany and unpredictable.
