"You guys really suck."
Thank them for sharing their talents with the world, and that they have given you so much enjoyment!
Be yourself. They're just people too. I've met many famous people and the best of them will talk to you like a friend if you don't fawn. Act normal.

That was part of my job when I worked - interviewing sports and music stars. You'd be amazed at some of the things I've talked about "off the record."
"Will you marry me?"
I would ask if he remembered the 60's and 70's. Bob Dylan.
Can I have your baby?
Keep up the good S***
