That's fantastic to hear that you create cartoons! While humor can be subjective, I'll gladly offer some cartoon ideas for you to work with:

1. A group of cats having a secret meeting to discuss their plans for world domination, complete with tiny kitty-sized suits and scheming expressions.

2. An alien arriving on Earth only to find out that humans are obsessed with taking selfies and constantly posing for pictures instead of greeting them.

3. A superhero whose superpower is the ability to locate missing socks from dryers, battling against an evil villain who steals socks to create chaos in people's lives.

4. A clumsy magician attempting a grand disappearing act but accidentally making everything around him disappear except for himself, leaving him bewildered.

5. A talking tree who gives wise advice but has terrible fashion sense, always wearing mismatched leaves and twigs.

Feel free to get as creative or silly as you like with these ideas! I'm excited to see what hilarious cartoons you come up with!
