(FullMetal Alchemist) Greed:

"Well it's the same ass."

Sorry about the swear, but seriously my sister and I were rolling on the floor laughing. It started out like this:
Old Man Foo jumps in and saves Greed/Ling Yoa.
Greed: You came to save ass!
Foo: I did not come to save your ass, I came to save the young prince's ass.
Greed: Well it's the same ass.

End
