Class Excursion

I'd just collected this 8-yr-old boy from his class, and we were walking to his lesson.

Boy: Did you know my class is going on excursion soon?
Me: No, where are they going?
Boy: Ummmm.... I'm not sure.  I'm going to Germany, but they get to go on excursion.
Me: I think you got the better deal here.
Boy (starts giggling): Yeah...

Casket Case

The quartet girls all unpack their instruments on the desks.  Packing away her cello, the 9-yr-old said:  It's like a casket.  So, it's like I'm having a funeral.  For my cello.  Awww, so sad.

And all 4 of them start singing the Imperial March from Star Wars.

Psycho/Psychic

Handing out stickers to my string ensemble students.  The next girl's folder has green and silver stars around the name tag, with silver at either end.
9-yr-old girl: Could I... please... have.... ummm...
Me: ...a green star?
9-yr-old, indignantly: How did you know that?! You're not psycho!
Me, laughing: Ah - do you mean psychic...?
9-yr-old, startled: Oh!  Yes.  Sorry.
