You ever stand in line for an autograph? I did when I was a kid, and I really enjoyed getting that close to Leonard Nimoy. I still have the autograph. Getting it was a little moment, but still special. As @JonnyQuest037 said, it's like the cast taking a bow; their names are also on the program, you know. But it's also like getting an autograph from everyone, because that's pretty much literally what is was. That made it a special moment. I wouldn't want it the other way. I frankly don't care what the characters' handwriting looks like.
