This is being sought by a friend of mine, whose mother used to quote it to her child in the 1950s onwards. There's a bee which is so loaded with honey it's very tired, too tired to fly home so has to walk, then something about some other creature, maybe even another bee offering to help carry it, but possibly wanting to steal it/get credit itself for collecting it. She can remember only 2 brief bits 'too tired to fly, she had to walk' and 'I've such a load of honey'
