This is only one example of four that I've found...
Viewing Simon's Cat in 'Fowl Play' leaves me with a ytimg.com Plug-Ins item in Safari > Prefs > Privacy > Details.
Simultaneously, s.ytimg.com appears in (Safari > Prefs >) Safari Cookies > Flash Cookies.
Further, I find /Users/artie/Library/Preferences/Macromedia/Flash Player/macromedia.com/support/flashplayer/sys/#s.ytimg.com/settings.sol.
And, finally, clearing the Flash Cookie with Safari Cookies clears [...]/#s.ytimg.com/settings.sol.
I've got absolutely no idea how I stumbled on this, but I'm beginning to feel like I've swallowed my tail, it's come out the other end, and I'm working on a second swallow.
