This is even true regarding different religions. While some religions seem to have nothing to do with one another, the same lies can be found in them. Case in point: Mormons vs. Muslims.
This "Lutheran Satire" video comes from a Lutheran pastor. You may not be able to read all the quotations comparing the Qur'an with the Book of Mormon, but they demonstrate parallel teachings. You can take a look here.
Note: You might find the presentation a little hokey, but please overlook that. Lutheran Satire is meant to teach through entertainment. This would certainly be presented differently in a Bible Class or in a lecture hall.
