I'm loose jointed, so I often do things that other people can't physically do without realising it (leaning on my wrists because my hands bend too far to lean on them, sitting on the ground with my knee slung over my shoulder, etc.) It earns me many weird looks.
I have enormous boobs, so I pretty often get the old *guy looks at my face, eyes dart downwards, eyes come back up*.
And my eyes are very interesting, they look brown, but if you get quite intimately close, you can see that they're dark blue. I've always thought it to be quite romantic, although admittedly my husband didn't notice until he proposed to me referencing my brown eyes and I had to correct him.
