My father does pencil portraits of famous people and to complete them he seeks to have them sign it. So I am 1 degree of separation from some famous people, I guess.
Most famous of which is the Dalai Lama, others are more "locally famous" to Portugal like a couple of marathon runners who won Gold at the Olympics, a former prime minister, etc.
As part of the signing and stuff, I got to meet Dr James Watson (as an interpreter for my father), the guy who got the Nobel for being in the team that discovered the double helix nature of DNA.
