I can see it now when the waitress comes over ....

Waitress: "So how do you guys know each other..."
Us: "We're part of an internet forum"
Waitress: "What kind of forum is it"
Us: "It's for extremely horney people and their non-horney spouses"
Waitress: "So you mean it's just a forum for normal, married couples...."
Us: "Um, could we get some more water please."
