A few weeks ago, I was set up to sell pens at a local craft show. A guy walked up, looking over my pens, he asked, do any of these pens write under water? My response was, " no I don't believe so". To which he said " that's too bad, all my pens write under water, of course they can write other words too". LOL, he gave me permission to use that line, it might sell pens he says.
