Long "Lost" Twin?

    Yesterday I was out running a couple errands and while I was out a girl at the check out counter at JoAnn's looked at me and said "has anyone ever told you that you look like the Doctor from Lost?".  I laughed and said "yes!".  It happens all of the time, random people and a lot of my coworkers tell me that I look like Juliet from Lost.  I sometimes see a resemblance and take it as a compliment.  What do you think?
