If you were stuck on an island for 3 weeks, name ONE thing that you'd want to have on you?

One thing. All that you have are the clothes on your back and a pocket knife. (think Survivor).

I thought of this question awhile back when it was 10 at night and I couldn’t find my toothbrush. I went to bed, woke up the next day (with a layer of fur on my teeth) and proceeded to brush my teeth with a brand new mascara brush (el desperado).

So, for me, a toothbrush. I may smell like a polecat, but at least my teefies will be clean.

You?
