Alright! Why a duck? Why that...why a duck? Why a no chicken?

Well, I don’t know why a no chicken; I’m a stranger here myself. All I know is that it’s a viaduct. You try to cross over there a chicken and you’ll find out why a duck.

You should ford over the river.

I am guessing you have to duck under the viaduct if you are playing chicken
