When I was doing a course last year the group had to do a get to know you exercise. The females had to select something from their bags, and the guys something from their pocket, we had to show and tell how it related to our personalities.
I had my practice CD from my stage show at the time so I used that, there were some hilarious exhibits though.............spanners, spare shoes, even a paintbrush! It was a fun icebreaker.
