I was 11 in 1991. I remember a couple of things.
The "Video of the Year" was R.E.M. "Losing My Religion" although "mama said knock you out should of won.
The girl i have a crush on tells me that soviet forces storm Vilnius to stop Lithuanian independence and she is worried about her family back home. The Gulf war starts shortly there after.
The United States Department of Justice announces that Exxon has agreed to pay $1 billion for the clean-up of the Exxon Valdez oil spill in Alaska (which ruined my school project)
Mike tyson Gets arrested, the same day The Super NES comes out in my hood! Russia falls apart shortly there after.
Magic Johnson announces he uhm.. spread his magic around to much...
And thus the "90's" begin and everyone goes around saying "Whats your problem this is the 90's now..."
