It's really an old thread. There is a joke between my English teacher and me.
Student A: Miss Hanna, I remember that the freeze point is also named as "Zero point".
Miss Hanna: Yes, the physician made a decission that 100 is the boiling point and 0 is the freeze point for water.
Student B: Miss Hanna, Zero has his view.
Miss Hanna: Yes, Mr Zero, I don't mean you.
Zero: I see. Only Ciel call me Mr Zero before. So I cannot follow.
