I have a student named Nico in my fourth grade class. He is a native Spanish speaker, and his English is pretty good. However, he is a funny kid to begin with (his hair is always a mess, his belongings are everywhere, his is very distracted and never quite where he is supposed to be) and then he says interesting/hilarious things that are really just language mistakes. Here are a few examples...
Me - "Nico, you are an odd duck!"
Nico - "What? Odd duck? I thought ducks only came in evens."
Me - "Nico, you need to be in this room in ten seconds."
Nico - "What?"
Me - repeating Nico, "What?"
Nico - he laughs, "Ha, now I have a slogan!"
Me - "Nico, you better put those erasers in your pocket or you're going to lose them in the museum."
Nico - quickly drops everything all over the parking lot, "Well, I guess its a tradition!"
