Oscar The Grouch is very grateful for this Father’s Day. Over the past few months, Oscar’s grandfather (David’s father) has been having heart issues. On Wednesday he had heart surgery, and the swissy is very happy that everything went well. There were many days during his puppyhood when Oscar stayed with his grandfather in Brooklyn, and they both would of been devasted if the surgery did not go well. Oscar looks forward to his grandfather’s release from the hospital once some post-surgery issues clear up.
