Do you guys have or know someone with any weird body parts or can you do anything weird with a body part? Do you have any strange birth marks, etc?

I have a friend who was born with 6 fingers and she had to have one removed when she was little, and I have another friend whose younger sister was born without a thumb on one hand. As for myself I have really weird pinky toenails, they look like little mini spikes or something but it's not that noticeable, runs in the family. I have two tiny white bumps on my body, one near my shoulder and one by my ribs but I don't really have a clue what they are. When I was little my dad called them Princess spots to get me to like them more because I used to hate them haha. As for birth marks and stuff, I have a heart-shaped mark on my right arm that I've always liked.
