pins and needles, needles and pins there's a giant dog who learned how to grin. He gave up his bone for a lesson in smiles, forgot to eat, and walked for miles. when he got to the class skin and bones, teacher took pity and gave him a loan. He learned very fast, the teacher was proud Now he's a dog who grins very loud. If you see a large dog talking with men, There's a very good chance it's the dog with the grin.
