Histeria!

Chit Chatterson:
Okay, you want something fierce?

Ivar the Boneless:
Well, that's the concept! Something that'll strike fear and make entire nations surrender and bow to us!

Chit Chatterson:
I have just what you're looking for - the dreaded dragon! [reveals a figurehead of a duckling]

Ivar the Boneless:
No, that's not a dragon.

Chit Chatterson:
Sure it is; a fire-breathing dragon! ROARR!

Ivar the Boneless:
No it's not, it's a duckie!

Chit Chatterson:
Excuse me! Hello? A duckie? Earth to Boneless! That's a fire-breathing dragon!

Ivar the Boneless:
With a beak and feathers?!

Chit Chatterson:
Have you ever seen a real dragon?

Ivar the Boneless:
No.

Chit Chatterson:
They have beaks and feathers!

Ivar the Boneless:
Not on my ship, they don't!
