thought of the day 2009 07 15 - glasses

I wear glasses, which is generally okay except I have to take them off when I swim. What I wonder though is whether I would need to take them off when I become famous and do a stage dive into a crowd of people and just people surf for a while? Do I have to take them off? And if I do, what would I do with them? Could I get a roadie who would just stand there and hold my glasses while I people surf?
