If you're funny, you can make money in the humor markets. Many mainstream consumer magazines carry the occasional humor article or column. A fair number of them also use humorous fillers. Study the magazine racks at your local bookstore to see what's being published. Whether it's a craft, sporting or general interest magazine, they usually have humorous opinion pieces on a regular basis.
Many publications reserve a column or two for simple amusing articles.
Unlike books, magazines don't require that you submit an amazing query and await a response. Rather, they have no idea if you're funny. Most editors ask that a sample of your work, or the completed humor article itself, be included with the initial query letter. Again, don't forget a self-addressed stamped envelope.
