When Fat Cobra throws Monkey he calls it a Fastball Special. This was originally a move used by Colossus to throw Wolverine into battle
At the 18:48 mark of the episode they use the quote " May the road rise up to meet you, may the wind be always at your back. May the sun shine warm upon your face. May the rain fall softly upon your fields, until we meet again!" When Monkey buries the gun. This is an Irish blessing. For a show based in Japan that has several Asian characters that have Asian accents and many that are American to ignore the many Japanese blessings of death seems like a missed opportunity.
