This short (less than 3 minutes) TED talk by Derek Sivers would make a nice follow-up to any discussions you may have had recently with your students about Steve Jobs and the Apple “Think Different” campaign.  It reminds us to think globally and to try to look at things from other perspectives.  Before showing the video, it might be nice to ask your students if they had ever witnessed something they thought was “weird”.  After the video, you could revisit the pre-discussion, and see if the students can think of reasonable explanations for those “weird” sights or behaviors.  Alternatively, have them develop a list of their own behaviors that others might perceive as “weird”.
