I know, it's not the "I Have a Dream" speech, but not everyone is Dr. King, but people make speeches all of the time for different reasons that can be inspiring (or not, depending on how you interpret each message).
For your initial response: determine the Audience, Purpose and Occasion for the following video, and then note whether or not Kutcher uses ethos, logos and pathos in his speech, and how he uses the elements you identify. Finally, say whether or not you think he was effective in his speech, and why (ex. how did he format his speech to help build his logos or ethos? How could he have better formatted his speech and why?).
In your reply: ask your classmate a question about his/her post regarding his/her thought-process regarding one or more of the determinations he/she makes (ex. "Do you really think his audience was the people sitting at the Teen Choice Awards or were they the people sitting at home?).
