I'm the queen of almost-inappropriate songs for kids in that age group. Here are some quick ones , all of them to the same tune. I'll give you the one you probably know first -- and hey! It's locationally appropriate:
Oh, I wish I was a little dirty bird
Oh, I wish I was a little dirty bird
I'd cross the Delaware
Without my underwear
Oh, I wish I was a little dirty bird
Oh, I wish I was a little blade of grass,
Oh, I wish I was a little blade of grass,
Well, along comes a doggy
And he makes me really soggy
Oh, I wish I was little blade of grass
Oh, I wish I was a little bar of soap,
Oh, I wish I was a little bar of soap,
I'd go slippy-slippy-slimy
Over everybody's heiny,
Oh, I wish I was a little bar of soap.
Oh, I wish I was a little piece of glass,
Oh, I wish I was a little piece of glass,
I'd go cutty-cutty-cutty
And make everybody bloody
Oh, I wish I was a little piece of glass.
And this is why Threnody is no longer allowed to chaperone school trips.
