Quick American Pie speech:
Maybe it's my age, I was 16 when this came out, but this is the best teenage movie since the John Hughes films and there hasn't been a better one since (and American Pie 2 is right up there as a great sequel).
I remember seeing this in the theaters and being on the floor laughing because it went to spots that no (at least popular) movie had before. It summed up exactly what you were doing/thinking about as a teenager in 1999 and the characters were all extremely relatable with maybe the exception of Nadia (unfortunately slutty Shannon Elizabeth was not in my HS).
This movie is in my top 5 of all time, no matter what category. I realize I am in the minority on this but if you were like 15-18 when this came out, this movie really hit home.
...ok back to Pi Day, yay.
