Enraging a group of Kobolds

Dear Epic Words,

I require your assistance with something.

Picture the scene:
A group of adventurers is making their way through a dungeon. The room ahead is filled with a group of kobolds. The Priestess of Avandra tries to solve everything in a diplomatic way, and it ticks the Goliath Warden (me) off. She is already (or soon will be) in the room with the kobolds to discuss our safe passage.

With what sentence would a Goliath Warden get the group of kobolds so enraged past the point of a diplomatic solution? I wanted to do this in an RP way, instead of just hurling my greataxe into their faces.

I already have some idea's written down, but I think most people here are able to think up a couple more.

Interesting question! I, personally, would go with a backhanded compliment of some sort. Kobolds are related to dragons, so maybe they're sensitive to being referred to as lizards or iguanas?
"My, my! What a fearsome looking bunch of geckos!"

Goblins and Kobolds have a long history of open warfare and Kobolds are usually more of the sneaky and clan-oriented kind of race. Some whispered comment but lout enough to hear should do the trick: "You better make this work, this clan of inbreds is too stupid for their own good, even for a race of complete cowards. The way my folks smashed their heads in during the xy war, we might have a lot of corpses on our hand if you can't convince them. And kobold meat is so stringy. Except for their eggs, think I'll get some of those."

"Except for their eggs, think I'll get some of those."

How would you like those eggs? Scrambled or poached?

How about "Get some big ones! I need a couple of eggs for breakfast."

You could also insult their mining skills. I've been under the impression that their ability to make mines and traps is also a point of pride for them.
