May Conversations: Maids and Fish

Grandma: Are you ready?
BH: I am readymade!

Did he mean, "readymade" or "ready, maid"? If the latter, well that's awfully rude of him to treat Grandma that way!

Grandma: You are not to be selfish!
BH: ::runs into the kitchen:: I want to see selfish!

No matter what the fish, it should be cooked or swimming in a tank, I suppose.
