"creative"/"fun" activity to introduce college freshman toSL...

Hi EVERYBODY!
I have been asked to give an info session at our Summer Freshman
Orientations about Service Learning.  I have one hour.  While I intend to 
tell about what the SL Office does here (America Reads/Alternative Spring 
Break/Walk-in Volunteer Resource Ctr/Faculty Dev in SL)--whech will take 
all of about 10 minutes--I have been trying to think of an activity that 
entering freshmen might enjoy that gets them thinking about Service 
learning/community service and lets them interact w/other new students.
      I tend to be really good at coming up with reflection/cerbral type 
things, but have a hard time finding games or activities that freshman 
enjoy and don't think are dumb or too touchy-feely.  Also, I need something 
that doesn't require money or too many "props"!
If you have ideas or resources, please send them to me at 
kkjohn01@gwise.louisville.edu 
Thanks,  Kim Johnson/Service Learning Coordinator at the University of 
Louisville.
