Seriously though, I have met quite a few posters on SF through work. We would start chatting about what we liked to do in the evening. I never gave too much away, but many were keen to brag about how they had been arguing with someone the previous night on SF, and the fantastic put downs they had come up with!
I used to make mental notes of what they told me, then go and see if I could identify them on the forum! Great fun, and I identified at least two thirds of them!
I have also been on an organised walk with fellow posters, and had a great time, with great people.
