I've had a few "Friend Suggestions," that there's just no possible way the website could know there's any connection between us. An old classmate with no mutual friends, (never listed schools in my profile,) coworkers, (never listed place of employment/no mutual friends,) etc. I'm thinking this is another good reason in favor of deleting my facebook. It's also a little embarrassing, because I've totally "stalked" people I hardly know because I am HORRIBLE with remembering faces. So I know if I'm going to see a certain person, I'll just take a quick look at their profile so I don't accidentally completely ignore them.
