Lullaby

I know all the words that Bono has penned, but when it comes to nursery songs, I'm a little lyrically challenged. I just put Baby C down for a nap, with something along these lines:

Hush little baby, don't say a word
Papa's going to buy you a mockingbird.
And if that mockingbird don't sing,
Papa's going to buy you a diamond ring.
And if that diamond ring don't . . . don't... shine?
Papa's going to buy you a, er, a circus mime.
And if that circus mime should speak
Papa's going to buy you a ... chimpanzee.
And if that chimpanzee should... should... sneeze,
Papa's going to buy you a new set of knees.
And if those new knees should ... crack?
Papa's going to buy you a juicy Big Mac.

Funny how she doesn't seem to like it when I sing.
