Thanks, everybody! And thanks, Joe for the (as usual) extremely helpful information!! Not that anyone (but me!) cares, but I spoke to a friend who knew the words to Little Nellie Kelly:

Little Nellie Kelly
Had a pimple on her belly
So she went to the lady next door

The lady next door
Put some jelly on her belly
Now she doesn't have a pimple anymore!

For some reason, this one used to crack me up as a kid! (Hope I did the line breaks correctly...)
