What's so bad about having a kobold in your family tree?
Nothing, as long as you're cool being related to a yappy, dirt-digging coward who used to be worth 7 experience points back in 2nd Edition. And who even probably knew how to read.

You seem awfully literate for a kobold hating goblin, friend.
That's ok though. We in the Kobold Defense League believe in turning the other check. In fact, I'd like to invite you and your goblin friendshorde associates to visit our offices. We are always open to new faces to test tour our Dragon Temple and Trap Extravaganzorium tm
