top 4 Reasons we know Mokuba's older than Seto lets us think he is

4. No one that young could sneak past about 2,794,614,274 security personel into Duelist Kingdom.

3. He did a good job tackling those carnival folk.

2. He's head of security in Battle City. I mean, Seto's not stupid. He wouldn't put a 10-year old in charge of security.

1. He's taller than Yugi.

0. (fine, this makes 5 reasons. I just thought of one at the last minute) He cross dresses. Just look at him in that stupid game Seto made!
