Final answer:
The funniness in a humor appeal should be directed to the audience's value system in order to be successful.
Step-by-step explanation:
To be successful, the funniness in a humor appeal should be directed to the audience's value system. This is because humor that resonates with the audience's values is more likely to create a connection and engage them. The humor should be relatable and align with the target audience's beliefs, attitudes, and interests.
For example, if the target audience of an ad is environmentally conscious, the humor in the ad could revolve around eco-friendly practices or sustainable living. By doing so, the humor becomes relevant and connected to the audience's values, increasing the likelihood of a positive response.
