Histeria!

Ivar the Boneless:
My brothers and I are leaving on a six-month loot and pillage of England, and we're looking for a ship with a savage countenance.

Chit Chatterson:
Well, Boney, you've come to the right place! I've just the thing - one of our big, BIG sellers! On sale today only, we call it the terrifying King of the Jungle! [reveals a ship with a kitten figurehead]

Ivar the Boneless:
It's a kitty!

Chit Chatterson:
No, it's a ferocious jungle cat! ROARR!

Ivar the Boneless:
It's a kitty! I can't invade England with a kitty on the front of my boat!

Chit Chatterson:
Are you kidding? This thing will strike terror in their souls! It will send people running!

Ivar the Boneless:
Only if they're allergic to kitties. I need something fierce!

Chit Chatterson:
He's fierce!

Ivar the Boneless:
He's smiling!

Chit Chatterson:
No he's not!

Ivar the Boneless:
That's one of those inscrutible little kitty smiles!

Chit Chatterson:
No, he's thinking!

Ivar the Boneless:
[sarcastically] Oh, thinking! Great! "Here come the Vikings, they're going to think us to death! Oh, my brain's filled with thoughts! Run for your lives!"

Chit Chatterson:
Now now, Boneless baby, look at those eyes! They say, "I'm angry!" They say, "I'm dangerous!" They say--

Ivar the Boneless:
They say, "Meow," he's a happy little kitten!

Chit Chatterson:
I happen to know he's not the least bit happy. He's actually rather sad.

Ivar the Boneless:
Oh, even better! "Run everyone! Here come the Sad Kitty Vikings! Look out or we'll depress you! Ooooh!"
