Black: *brings home a bucket of lobsters* Hey Zamasu, will you cook these for me please?

Zamasu: Black do you really expect me to cook all of your meals for you?

Black: Yes?

Zamasu: *hits Black over the head* No! I'm not going to cook all your meals for you, you need to learn to do it yourself!

Black: *rubs his head* Owww.....

Zamasu: Hmph!
