As much as I enjoy FFX, I've been reminded of how many things Tidus in particular will say that makes me cringe. These kinds of lines probably existed in older FF games, but I think the move to including voice acting in this game helped to kind of highlight some of the more awkward things people say. Two I've encountered so far in this play through:

"I made it out of the frying pan... and into the freezer!"

"Crews of what?"
