Alzheimer’s and diarrhea. You’re running, but can’t remember where.
Explanation: This joke plays on the absurdity and dark humor surrounding the combination of Alzheimer’s disease and diarrhea. Alzheimer’s affects memory and cognitive function, while diarrhea involves frequent trips to the bathroom. The punchline humorously highlights the ridiculousness of being unable to remember where to go while needing to run to the restroom, creating a comedic yet slightly uncomfortable scenario.
