When I was very young, my heart belonged to Spock, but I knew I wanted to marry Kirk, as Kirk was a Captain and Spock was only a first officer. (Hey, I was 4 at the time!) That lasted until I was about 7 when I became infatuated with Buddy Ebsen in Barnaby Jones and Jack Klugman in Quincy M.E.
Somewhere in middle school, I discovered Abraham Lincoln and Francis Marion and those were my real adolescent crushes, although I kept my crush on Spock into my college years.
Of course, I did have a certain sweet spot for Pierce Brosnan. Even today, I don't think I'd kick him out of my bed for eating crackers.
