Corrected entry: I know its just an expression but if you listen to Peter Gallahger in New Hampshire he says "Let's go dot all the i's and cross all the t's". If you look you will see that there are absolutly no i's or t's in Adam Sandler's character name "Longfellow Deeds".

Correction: If you listen closely, he says dot the t's and cross the i's.
Correction: That's the most ridiculous piece of "trivia" I've ever heard. As you yourself say "it's just an expression". It has nothing to do with his name.
