Things that are funny may be described as amusing, witty, and/or humorous. PPCers strive for this in their works, and much of what happens to PPC agents is governed by the Rule of Funny.
Things that are funny may also be described as odd or a little bit off. PPCers also fit this description.
Many things that have often been described as funny are merely stupid or dumb. PPCers ought to know the difference between this type and the other two types. Badficcers often don't.
