Just for the record, here are two comments about the "U-G-L-Y" comment from a Mudcat guest:

Teaching English is Spain and my students love these types of rhymes the best. Originally from Boston surprised not to see:

U - G - L - Y
You ain't got no alibi
you're ugly
that's right
you're ugly

There is a second phrase about "your momma", but I don't remember it.

I heard the "ugly" chant in Boston in various summer camps in the late 70s. I've always assumed its even older than that...

There are lots more children's playground rhymes that include spelling. Does anybody else want to share some?
