Nothing is more off-putting than the use of crazy fonts in professional documents. They also have implications for product advertising.

In terms of professional documents, the use of crazy fonts like Chiller or Jokerman detracts from the air of professionalism the writer is trying to convey. Crazy fonts not only make the reader unsure about the seriousness of what the writer is trying to convey, but can also make the reader call into question the maturity of the writer. These two distractions can kill both an article's argument, as well as possibly the writer's career. If a recruiter receives a resume written in a crazy font, the probability of them just throwing it away without reading it is exponentially higher. In a professional document, a professional font is what is called for in every circumstance. The default font should be Times New Roman and the size should be 12 point which indicate the writer is aware of professional conventions, is willing to adhere to them, and his or her writing should be viewed by the reader as serious.

The use of crazy fonts in advertising can be used effectively in order to create a particular tone or mood that the advertiser is trying to associate with their product or service. A particular font like Jokerman can help associate the product or service being advertised with a sense of whimsy or a playful attitude. This would be appropriate in advertisements for children's toys or an amusement park, but it would be inappropriate for advertisements for a new diabetes treatment or a funeral home. The use of crazy fonts in advertising does run the risk of bogging down the effectiveness of the ad, though. A font such as Vladimir Script is difficult to read, and may cause confusion as to what is being advertised. This confusion would certainly detract from the ad's effectiveness.

All in all, it is better to be safe than sorry. Because of this, a writer should avoid the use of crazy fonts, unless they are very sure that it conveys the tone he or she is intending
