"I Seldom........."

I don't see it recently but wasn't there an internet meme: "I seldom XXXX but if I do (or when I do), it's YYYY", something like that??

I seldom catch big fish or I don't consider myself a "big fish guide". I'm just a dry-fly guide (who uses bobber every so often). But If I do assist my clients catch big fish, well, that's good!!
