This whole celebrity worship is so weird, but it's been around for a long time, sometimes obviously to a worse extent like emperor worship or living deity spiritual leaders' worship (which is still around).
I do like some prominent people myself, but I like to think of them as human like me. I think the worst thing I have is that I like some famous hotties and think too much about them. Television and movies do present some of these people in such favorable light that it's hard to resist the urge to think of them as more than just people.
I had my picture taken once with a couple of celebrities, but I didn't get butterflies in my stomach, it was pretty much normal. I guess that is a good sign that I am not totally sheepish.
