Mine isn't as glamorous. I sold a hammer to Don Henley (The Eagles) in Aspen. I worked at a hardware store there one summer.
One fine day, a couple came in to do some shopping. The lady was, um, rather attractive. I didn't take much notice of the man. After they left, a seasoned Aspen resident co-worker informed me who I just sold a hammer to.
That same summer, my girlfriend there saw John Denver at the open-air mall. That shows you how long ago it happened. Another friend was a maid at a condo complex, and she cleaned the suite of the president of Sony.
