Okay, now that I know I'm a boy on a "girls-only" thread, I have to ad this link:
The Go Girl
My "office little sister" ordered them for a road-trip she went on but failed to tell me they were coming to the office for her personally and not as... office supplies I guess. In any case, she was more than tickled to show them to all of us, and there's no forgetting that product name.
I'm not sure if this would be more or less useful than a hat, but if you found yourself having to do a 24ufc and a road trip all at once, or if you just want to give everyone in the office a chuckle, this might work for you.
I gotta say, collection is another one of those instances where it really seems like it's easier having boy-junk rather than girl-junk.
