Writing Comedy

Humor is an elusive thing for some writers, and comes naturally to others. Either way, it is very hard to explain comedy, for the same reason that jokes aren't funny when you have to explain them. But I'll do my best.

Irony has three meanings: Verbal irony, situational irony, and dramatic irony. 

Verbal irony is saying one thing to mean the opposite. It's basically sarcasm. This can be very helpful in creating funny or witty dialogue.

Then there's situational irony. This is used a lot in sitcoms. You expect one thing to happen and get another. For example, your high school mean girl says. "I am a nice person!" and then stomps on someone's foot. Or your strict principal commends you on your brilliant food fight. 

Lastly, there's dramatic irony. This is when your audience knows something, but your characters don't. A good example of this is The Son of Neptune. It's part of a series that is a sequel to the previous series starring the protagonist, Percy Jackson. In The Son of Neptune,Percy has lost his memory. The audience (at least, the ones who read the Percy Jackson series) know all about his past, but he is oblivious. I don't know how you would adapt this concept to make it funny, because (plot twist) I couldn't write dramatic irony if my life depended on it. 

Now, humor is more than just irony. Teasing is funny, as long as you aren't being mean. Some people find farts immensely funny.

Basically, whatever you find funny, work into your writing. And have fun doing it!
