Theme shoot

I met up with one of my photographer friends.  And we were discussing what sort of shoot we should do.  We've been trying to get together for a informal photoshoot for the longest time now and finally we are both free.

Anyone has any suggestions as to what kind of themes we should try out?  And please, no provocative ones (or at least too provocative).  I don't know, anyone has any ideas as to what theme might suit me? :)  I'm open to ideas.

Hopefully we can get the details sorted out and start shooting sometime this week.  It's been dragged on for too long.  He wants to stray away from the usual casual shoots and move towards something perhaps a little more artistic, themey, and costumey maybe.
