Pink pajamas

I wear my pink pajamas in the summer when it's hot.
And I wear my flannel nightie in the winter when it's not.
And sometimes in the springtime and sometimes in the fall I jump between the sheets with nothing on at all!

Edit: new verses learned from Aunt

Glory, glory what's it to ya?
Glory, glory what's it to ya?
Glory, glory what's it to ya?
With nothing on at alllll!
