Talking about marriage in class

One day a teacher was talking about marriage in class.

Teacher: What kind of wife would you like, Tony?

Tony: I would like a wife like the moon.

Teacher: Wow, what a choice...Do you want her to be calm and cool like the moon?

Tony: No no...

Teacher: Oh, so you want her round and white?

Tony: No No...

Teacher: Or maybe you want her to be fair and beautiful?

Tony: No No No, I just want her to appear at night and disappear in the morning...
