Easy way to create 100 instance of same MC?

I know for sure this is a stupid question, but I’ve never come across this before, so please forgive me for asking :wink:

What’s the best method to put 100 (or 25 or any large number) of movieclip instance on stage & give them all the exact same onRollOver event/function ? Ofcourse with the fewest possible lines of code.

Any kind of hints/advice very much appreciated. :slight_smile:
