Do you have an interesting question for the ninja? Here are some by M Koosman and Andy B:

How do ninjas prefer to kill zombies?
When ninjas kill other ninjas, do they use white out?
Do ninjas feel embarrassment when they get leafy greens stuck in their teeth?
What noise annoys a noisy ninja?
Andl lastly: Ok, there's a hippopotamus and an alligator, a mongoose, a hyena, and a ferret and a butterfly (against a ninja?) who would win?

My question: How does a Ninja entertain itself while waiting for Godot?
Or? How does a Ninja deal with blood stains?
Or? Is there any sacred place a ninja is restricted from killing?
