Do you lose your mind and start jumping and shouting when you see a celebrity, famous person or etc. etc in order to shake hands, or click selfie.

I was at a comic-con and wanted to get an autograph from one of the Actors there. He play Captain Malcolm Reynolds in a small tv show Firefly. Had to wait like forever for the guy. To many people were going crazy over him and wanted personal photos and yarn to him. I was kind of disappointed he didn't sound like he does in the show.
