So, there's this one social networking site. You may have already been there. And if you're like me (and why wouldn't you be?) you might have got an ad for "Professional Singles". Which you might argue would be the same thing as "Single Professionals".
Or maybe not. Maybe it's people who make money being single. The only profession that comes to mind is prostitution, even though it's not quite right.
Maybe I should change my profile to say "Amateur Single".
