9. Michelle - American Pie
Alyson Hannigan is the girl that you marry. End of conversation. She's the perfect combination of sexy and cute as band geek Michelle. The character is a prime example of that girl in high school that for whatever reason you overlooked, until you finally talked to them and realized that they were probably the most awesome person on the planet. When we first meet Michelle, she's just this nerdy, overenthusiastic flute player who has a lot of really interesting stories from band camp. Jim barely even notices her. But as the film goes on, we start to see her for the genuinely cool chick that she is, culminating in their memorable prom night hook-up. Michelle might lack a filter in most social situations, but she makes up for it with her easygoing personality and sexually adventurous temperament. There's no other way to put it; Jim is a very lucky man, especially given the incredibly public performance issues he's had in the past. She might come off as a little bit on the aggressive side, but it's clear by the end of the film that she's a keeper. Which brings me back to my original point: Alyson Hannigan is the girl you marry.
