Never did find a Bossk myself, and I always lusted after the pictures of him on the cardbacks.
I distinctly remember my first figures: Luke in Hoth fatigues, Imperial Officer (bowling ball helmet dude) and the Taun Taun with the slit belly.
Now that I recall that memory, it's blowing my mind because it must have been either my second or third birthday when my mom gave them to me, since I know I had a whole slew of figures by the time ROTJ came out when I was four.
It's probably my first memory!
I had a tape of SW recorded from HBO, which I probably watched daily from age 2 to 4, and the HBO theme therefore calls up that SW thrill more than the 20th Century Fox fanfare. You know the one: do-do-doooo, do-doooo, do-do do do. Do-do-dooo, do-DOOO! Do-DO-DOOO!
Dunh! Dunh! Dun-nuh-nuuuunh!
