A friend of mine was telling me the "how they met" story of a friend of his, and it's too great not to share.
His friend was out mowing his lawn one day, when a woman came by on a skateboard. Assuming he was the yard guy, she stopped and asked if he wouldn't mind mowing her lawn when he was finished with that one. He complied, and continued to do so every two weeks or so for a while. He charged her $11 a visit.
He also neglected to mention until much later that he is actually the public defender for the city in which they live, and as such, not a yard guy (at least professionally...). And now they are getting married.
