I have sort of a mental list of all my claims to fame. Here are some examples:
My grandfather's cousin is a well-known local composer and music educator. He wrote a couple of hymns in the hymnal we use at church.
My high-school counselor's son used to be the boyfriend/drummer of Natalie Merchant.
My mother once sat next to Maurice Abravanel at a party.
I've shaken Thurl Bailey's hand.
I used to go to school with an Osmond nephew.
I knew the guy who plays the snotty blond guy in "Napoleon Dynamite" before he played the snotty blond guy. I went to high school with the girl in the glamor shot in that movie.
I also went to high school with the winner of the reality TV show "The Rebel Billionaire".
My classmate/colleague/friend will be running in the Olympics in Beijing this year.
As you can see, I'm somewhat indirectly connected to fame, but don't have any real claims on it myself. That's probably a good thing.
