It was a tubular experience

My dad had some rather serious surgery several years ago. After the successful surgery, my sister and I waited for him in his hospital room. He arrived still heavily sedated, with tubes seemingly coming from everywhere. We tried talking to him, but got no response. He was still very out of it from the surgical anesthesia. A short while later the nurse arrived. She gave him a quick once over, checked all of the tubes and whispered to him, “You look fine. I’ll be back to check on you again later.” As she was leaving, Dad lifted his head slightly and, with eyes still shut, in that post-operative, dry, hoarse voice, he said, “Thank you. When you come back, if you bring another tube, we can have lunch together!”
