Dear Teachers,

I do not understand these two jokes. Could someone please explain these for me.

1. What inference makes the following joke funny?
Sam: Do you know how to save a politician from drowning?
Joe: No.
Same: Good.

Texpayers like to dislike politicians, and this joke falls into that category. as a rule, when you have to explain the inference in a joke, the un is lost. You want your audience to make the connection and laugh uproariously.
--I quoted this from the book exactally. And I do not understand this joke.

2.What do you know about a jury? What is being implied about this cartoon? (I am sorry that I am not able to draw the cartoon here so I just describe the cartoon for you.) In the cartoon, there is a police officer taking order for the jurors. Below the picture, there is a sentence. "Eleven hamburgers, one "frank", Eleven coffees, one tea. eleven apple pies, one chocolate cake..."
--What does "frank" here mean?
--Also what make this cartoon funny?


3.What does "infectious wit" mean?

4.What does "home folks of rural America" mean?

Thanks:)
