I remember the phone number of my great aunt who lived in East Germany. It was a 12-digit number (including country code). We called her once, maybe twice a year, and usually my mother was dialling. I was maybe around 8 or 9 at the time (it was around 1988).

I cannot even remember the birthdays of people close to me, let alone any phone numbers except my own. But I still remember that f*king 12-digit international phone number from almost 40 years ago...

oh and of course I remember my ICQ number ;-)

Human memory works in a weird way
