The scene where the cheerleaders are fund raising by doing a car wash. Leslie is filming the car wash with his dad's new digital camera. When he gets to Missy, she has a sponge and is rubbing the car antennae. When Leslie see this he yells "Aaron, what are you doing?!" He called her by her real name, not her movie name.
I beg to differ! On the DVD you can put captions and Les says "Missy, what the hell are you doing? "
Missy Pantone is her movie name and her name in real life is Eliza Dushku!
You must be hearing things, because after reading your "slip-up", I watched the movie yesterday, and he said Missy! Plus her name in real life isn't even Aaron!
