Maybe it's only a matter of time....

Uh-oh....  I hope the greeting-card industry doesn't get funny ideas from the latest strip and start marketing "you're welcome" cards.  After all, don't they typically seize just about any opportunity to get people to spend more money on cards?  Hm.  Maybe I ought to jump in ahead of the curve and start marketing a line of  "CG and (N)J" "you're welcome" cards?  But only use them if you really want to mess with someone.  Next thing you know, the "Miss Manners" column will be overrun with people stressing over whether proper etiquette dictates a "you're welcome" card for every thank-you note received. ;)
