Man, I have to agree with Total Refected Power here:
Any of the 12 inch models were the best, not the stupid mini-ones they have today or that cartoon series which I tried to watch but just couldn't.
The Kung-Fu grip guys were fun.
Used to toos the parachute guy off the roof of my house: sometimes without his parachute.
Has the scuba and submarine guys for my pool.
I used to put firecrackers under mine to simulate artillry bombardments -- those guys took a beating.
I still give my mother grief over the fact that she never got the the G.I. Joe Training Center I wanted for Christmas one year -- and that was along time ago
TRP: Don't know if you ever saw this, but there was a short film made by a guy a year or two ago.
Can't remember the name but it was very cool and brought back a lot of memories.
It was basically a kids room that had all the different 12 inch models in it.
It's warm summer day so the kid leaves the room to go play outside.
When he does, all the G.I. Joes come to life and start having a blast in the room, they're driving their jeep all over, the parachute guy jumps off the bookcase, etc., etc.
It was really fabulous.
