How about some of these for size:
1)
That is a solid IOI. Still remember that scene up to this day.
2)
Another great IOI. This one is so good, I must have watched this movie once or twice in my life like 20+ year ago, yet I still remember this scene enough to have done a specific search. Especially if you are nerdy type of guy, you'll anchor into the character and see how that scene unfolds. The wet dream of the socially akward.
3)
Another obvious IOI here.
There are probably plenty of other solid IOI movie scenes, but these three really stand out.
