I was being tongue-in-cheek. Sometimes it's hard to convey over text.

I know signing the back of a credit card isn't at all required, and until recently I hadn't done it because of the inevitable smudging. On a whim I found something that works, and I suspect some of you will find it useful. Its a Sharpie Industrial Extra Fine marker. In my experience, this marker has provided a profound improvement on other markers and pens. I allowed a few minutes dry time, then attempted to smudge the signature with my finger to no avail. I'm quite impressed. Amazon is a good place to find it, and I suspect it'll be available at most office supply stores.
Those are the best. You can find them in most stores. The outside is silver and black striped, though.

95% of everyone here have a hard time reading sarcasm man. Not me though.
