Hmm...the best one I can think of, and this is not a joke is from the Odyssey...
What I heard...
"Try out for Champion of Ithaca, I will ride all the ropes, let the gods sing my song"
What it is
"Triumphant Champion of Ithaca, I will right all the wrongs, let the gods sing my song"
Oh, and in Fallen...
What I heard...
"There's no fourth graders"
What it is...
"There's no force greater"
