Matthew Perry grew up partly in Ottawa, not too far from where I live but didn't know of him at the time (though the current Prime Minister went to school with him; not sure if that's a good thing...).
I was/am not a fan of Friends, but Matthew was a great guy, and left us way too early.
Continuing with my "fame by (geographic) association"...Tom Cruise (not his full name: Thomas Cruise Mapother IV) lived in the east end of Ottawa next door to the meat manager at a local supermarket (who I knew and spoke to).
