My dad is retired from Verizon. When I was like 7 or 8 he fixed the phone in Whitney Houston's house. He got me an autograph! I still have it.
Also, I went to a Jimmy Buffett concert with my ex. They were throwing shirts into the audience, and I caught one. We were right up front, and Jimmy signed the shirt. But I gave it to him. Wish I had it back now!
