"In some cases, viewers may find the over the top version of a character more entertaining than their original, subtler version, and can also be a result of the author having more creative enthusiasm for the distilled version. There has been serious study on why this works with audiences. Philosopher Henri Bergson in his essay “Laughter” wrote that comedy is based on inflexible behaviour, i.e. living people acting mechanically in their trademark manner, however inappropriate the circumstances. Early examples: Malvolio (from William Shakespeare’s Twelfth Night) will always be self-important and anal-retentive and is thus easily gulled. Jack Benny will always be stingy, even with a gun to his head."
