A Reddit poster shows us why the fine print in a contract is so important. His landlord sent him his lease by e-mail, in MS Word format (which was editable) rather than a non-editable format like Adobe Acrobat (.PDF). Realizing this, the tenant made 'a slight change' to his lease before signing it . . . and his landlord didn't catch it. Now he says he's going to hold his landlord to it.
The comments from readers are a lot of fun, too.
