Ever since I was a child I had this strange idea that I was missing fingers (I have 10 like most). From grade school till middle school I even kept counting them as if something was amiss. I mean, it's not like it's actively bothering me or something, but just a bit of a curious quirk: I think I should have 12 fingers. Although in my case it feels like they should be to the side of my pinky, not between the index and thumb. As far as I know my parents didn't have them removed at birth either. Funny enough I believe the gene for it is even dominant (meaning it needs only one copy to express the phenotype), it's just not very common in the general populous.
