Here's Johnny - Every. Single. Time.

My usual reaction upon hearing Hanzo's spiel is "Oh, I hope that's one of ours…"
Usually followed by "OH, IT'S NOT ONE OF OURS".

Interesting thing I noticed is that the voice line actually differs depending on whose team he's on. If he's on the other team, it's the Japanese line. If he's on your team it's "Let the dragon consume you!"
This is actually true for all the characters.
