Poorly written comic-reliefs

A Comic Relief is the inclusion of a humorous character, scene, or witty dialogue in otherwise serious work, often to relieve tension. Comic relief usually means a releasing of emotional or other tension resulting from a comic episode interposed in the midst of serious or tragic elements in a drama.

Comic relief characters have existed since the beginning of sound cartoons, with Goofy from Disney's Mickey Mouse series being one of the first and earliest comic reliefs ever created in history of animation. Comic relief often takes the form of a bumbling, wisecracking sidekick of the hero or villain in a work of fiction, or even a comical main hero or villain. A sidekick used for comic relief will usually comment on the absurdity of the hero's situation and make comments that would be inappropriate for a character who is to be taken seriously. Other characters may use comic relief as a means to irritate others or keep themselves confident.

Some comic-reliefs can be done right and when executed to perfection, some of them can become fan favorites on the show. Take Roger from American Dad!, he is a done right version of a comic-relief, and he has become a fan favorite on the show. However, in a TV show or a movie, sometimes, comic reliefs can be considered pointless to the show or movie. Take Jar Jar Binks from Star Wars, he served no purpose in the film series, and he has received tons of negative feedback from fans of the franchise.

Most comic relief characters however are incapable of being the main stars of their own show or movies (unless that they are done right), and comic relief spin-offs like mh:terribletvshows:Planet Sheen learned that the hard way. However, the opposite case happens to some comic relief characters due to them having more complex personalities aside from just being comic relief which enables them to stand on their own as individual main protagonists in their own right, with Donald Duck, Goofy, and Dory being good examples of comic relief characters that are capable of being the main stars of their own shows or movies because of it.

How to make a well-written comic-relief

 * 1) Don't make a character way too goofy, stupid, and happy-go-lucky because making comic-reliefs are very hard. Some comic-reliefs are downright annoying, and are either bullies, pranksters, and troublemakers.
 * 2) Avoid making a joke that is very offensive to some people, and make it very simple and well-written.
 * 3) Also, give them some flaws, because some comic-reliefs have flaws too.
