Have you asked a Celebrity for an autograph?  

when I was a teenager I had an autograph book and had quite a few autographs of some local pop singers in it, I ended up selling it on Ebay..ahahahahh

I have been to many plays on Broadway but this one time I was able to get the cast to sign my playbook but I also took a picture with the star of the play. That star was Tony Danza. It was so exciting to have a picture take with him.

I really am not the type to rush towards a celebrity and believe me I have passed on many chances to be autographed by one.

I had my one chance when a famous actress attended the ordination of my brother and they happened to be friends so I kind of like had a very special privilege to have a photo with her. It's probably not as 'memorabilia stuff as an autograph but it was a great souvenir.

I know how being starstruck feels like.

I'm terrible at this. Usually, when I see a celebrity, I run the other way. I hate that a lot of people mill around him/her.
The closest experience I had was when I was in high school. I represented the school for a journalism contest. The guest speaker was a high ranking education official. For some reason, some of the students started asking her for autographs. And I did the same.
It was so lame.
