I ran across this story in a post comment about a guy who ended up babysitting a friends child on a first date, and charmed the hell out of his new lady. In my experience, seeing me interact with kids (without being awkward) brought me much more attention from women than I could get with direct interaction. In most cases, it wasn't planned, but in hindsight, I see clearly that it was a turning point.

Have any of you tried this? If not, this could be a huge, untapped gold mine--especially if you are already a father-figure to (well-behaved) nephews, neices, or your friends kids.
