... I will be honest and say that I did not even think of that when I was writing. ^^;

I was trying to think of a way Hermes could screw up a saying here since that is kind of a thing he does, and since it was about potential lying, I figured "Fool me once" worked well there. And feel seemed like a logical mistake there.

... "Feel me once, shame on you" does end up sounding [i]really[/i] dirty though...
