Here is an example of an advertisement which uses heightism to sell poorly made Japanese cars. As you can see, sexually humiliating and/or emasculating short men is a popular way to market goods and services through “humor”.
Also, you are given permission to laugh at their misfortune because they too laugh like naive fools at the end of the commercial. Don’t worry…no hurt feelings among any of them. They probably don’t even know what just happened. Because short people are stupid.
