Z-O-O

We went to the zoo today

J:  I can spell Zoo...Z-O-O

Me:  Yep good job

J:  What about the Museum of Play?

Me:  ummmmm what about it?

J:  Does that have a Z in it?

Me:  nope

J:  Why not?

Me:  It just doesn't

Then really quietly I can hear him in the backseat

J:  Mue-ZEE-um.....mue-zee-UM....MUE-zee-um

I was waiting for the "but it sounds like it has a Z."  I was disappointed
