Cana-What?

Last year's Junior Quartet begged to continue, so this year I get to take 2 quartets.  The continuing quartet started their rehearsals this morning.

Me: Does anyone have any requests for pieces you want to do? [A few suggestions were mentioned]
Cello: Oh!  Can we do that Mexican piece?
Me: Which one would that be?
Cello giggles, and tries to sing and play at the same time.
Me: The Mexican Hat Dance?
Girls: Yeah!  Oh yeah, let's do that one!  Can we?
Me: Sure.  You know, Mr B actually has it for string quartet already.  We use it for the mariachi band.
Cello [a bit shocked]: Is he Mexican?
Violin 1: Is he the tall one?
Me: Yes.  And, yes.
Cello: Is he really?! I thought he was from Canadia.
Me [smiling]: Um...
Violin 2: He's - what did you say?!
Cello: Oh NO!  Who says that?!  Where did I even come up with that?!  Oh how embarrassing.
