"Did you ever think that making a speech on economics is a lot like pissing down your leg? It seems hot to you, but it never does to anyone else"

Lyndon B. Johnson is expressing his belief that speeches on economics might feel interesting and important to the speaker, however they often stop working to captivate or impress the audience. The comparison to urinating down one's leg recommends a loss of control or efficiency, as the message does not reach the desired location. Johnson's statement suggests frustration or dissatisfaction with the reception of his economic speeches or those of others in this field.
