Simple really, and could be amusing. Name two things, be them from games or anime, and ask which is more lethal, and probable to kill someone. Example will be....
Akiko's Special Jam from Kanon
Sanae's Rainbow Bread from Clannad?
A punch from Goku?
A punch from Superman?
A slap from Naru from Love Hina
A mallet to the head by Akane from Ranma 1/2?
Okay, maybe they won't ALL be lethal, but what would definitely be closer to sending one to the grave? Answer, then reply with your own! Be creative!
A bearhug from Alex Louis Armstrong from Full Metal Alchemist?
A bite from Viral from Gurren Lagann?
