I had a colleague 20 years ago choose RoR for a multi-million dollar hospital software project despite the fact that he was the only programmer within 150 miles with even a rudimentary knowledge of it. I say "multi-million dollar" because that's what it ended up costing to develop it; the only revenue it ever generated was an initial $60K from the client, and even that ended up being refunded after three years and a system that still didn't work.
I wasn't on the project myself, but I did get to sit in on a client meeting where this guy said "but we've written six times as much test code as application code" and expected that to somehow mollify the client.
