And Another *drops mic* moment-#mr.ford

Student: Mr. Ford, I can not believe they have place  me in  lower Level Class. In my country I study English for only just one years, and I already know more than all the teachers in my countrys.
Me: Ok then, Umm...Let's try your vocabulary than, shall we? I'll ask you to use a vocabulary word from Level 7's vocabulary list. Are you ready?
Student: Yes.
Me: Use Catalyst in a sentence. :)
Student: Oh, very easy...'In Italy, there are many Catalysts.'
Me:What?? That doesn't even make any kind of sense.
Student: Sure it is. See, I already know more than you teacher. Everybody know that Italy is full of Roman Catalysts.
