Radek snorted. "My friend, I am not your dědek. I have too much of my own work to waste time doing your math for you. Please do not give me your boot."

Hee, I still love the dědek conversation. No old boots for Radek! (Possibly I am so thoroughly amused by this because my brain has been fried by academia, but still!) That was a good find. I always approve of random folklore tidbits. :)

Also, I love it when Rodney finds John and calls him "dědek" accusingly. And then tangled body parts and making out and future "collaborations", mmmmm.
