Power distance Puns

My Dad had a brain injury resulting from a fall and was in a nursing home for a year till he passed away. One of the things we both loved were "Dad jokes" and puns. When I visited him in the nursing home it was often a one way conversation. I would just ramble on not sure if he could hear me or understand me, but it didn't matter. One day I arrived and sat with him while he stared into the distance and I said, "Gees Dad you should see the weather outside it's raining cats and dogs and I damn near stepped in a poodle." He turned to me slowly and grinned and said, "That's an ollllllld joke", then he turned away and disappeared again. But for a few seconds he was there.....all of him. The power of Dad jokes. I miss him.
