Don't sing!

Morgan and I had a "Who's on First" moment the other night...

Morgan: Sing "Hush Little Baby"
Me: OK...Hush little baby don't say a word, Momma's gonna buy you a mockingbird. If that mockingbird won't sing...
Morgan: DON'T sing!
Me: Oh, OK. (quiet)
Morgan: MOMMY!! Sing the song!
Me: Hush little baby don't say a word, Momma's gonna buy you a mockingbird. If that mockingbird won't sing...
Morgan: DON'T sing, Mommy, DON'T sing...
Me: But you just told me to sing!
Morgan: What?
Me: You keep telling me "don't sing, don't sing"
Morgan: It's not WON'T sing, it's DON'T sing!
Me: Ohhhhhh, THAT's what you meant!
Me: Hush little baby don't say a word, Momma's gonna buy you a mockingbird. If that mockingbird DON'T sing...
