An old man dressed in a very aged, worn flight suit approached me today at the store. He had a question for me. He asked, ""Excuse me, Where can I find the cheapest Doctor in town?"" I just moved to a small military town, and before moving I worked at a hospital. While working there, my patients had asked me some pretty interesting questions, especially the ones who had dementia. So without hesitation I responded naturally and honestly: That I was new to the area and was not yet familiar with any doctors here. . Right as I finished my sentence he blurted out ""Dr. Pepper!"" and gave me a big toothless grin. . I misunderstood him again, thinking I heard him wrong and that he was asking where he could find the cheapest Dr. Pepper. I began to point it out-- As I began he giggled and repeated with an even bigger smile. ""No! Dr. Pepper! Dr. Pepper is cheap."" . I responded ""Yep it's cheap- Especially if you get the Dr. Thunder! (off brand)"" . He just kept beaming and saying ""Dr. Pepper"" over and over as he walked away. He then turned and gave me a happy wave goodbye. . Wasn't until after that I realized he had told me a joke. . **TL;DR** ""Dr. Pepper"" Also: Old men are adorable. And I'm really slow.
