Against Master Fung's instructions, Omi plays with the Ring of the Nine Dragons, which mystically divides its bearer into as many asnine identical twins. However, the ring also divides the bearer's talents, skills, intelligence, potential, etc.
Did You Know?
So why is Omi acting so silly?
The Ring of Nine Dragons divides you: your intelligence, creativity, potential, everything.
So that would make him...
Dumb as a sack of hammers.
