At the end of the movie where Ferris throws a baseball at the sound system to turn it off, you notice he throws it with his left hand (Matthew Broderick is really left handed too) but when the ball lands in the baseball glove on the floor, it is a right-hander's glove (i.e. it goes on the left hand).
I think in baseball you are tought to catch with you 'bad' arm and throw with your good arm, so if he is left handed he will catch with his right. (well I'm left handed and I throw like a girl with my right hand ;-))
Miss Venus and Shadow - read the last line of Stefanie's comment:
"ie it goes on the LEFT hand" - she is absolutely right, it should be a glove that goes on the right hand....duh!
This is a slip-up. They probably didn't want to bother to try and find a glove for left-handed people (I'm left-handed...those things are hard to find) and didn't really think people would notice that Broderick threw left-handed. Either that or they never bothered to care. Either way, it's not a big deal, or important to the story, but good eye.
well in baseball i throw with my right (since i'm right handed ) and i catch with my left and if i had a glove on i wouldn't be able to throw very well !!
