Memory Loss memes

I find it best to screw people with memory loss. I mean, what's my grandma gonna do? Describe me to the cops?

A man goes for his annual checkup. Afterward, he's sitting in the doctor's office, and the doctor comes in with the results of his tests. The doctor says, "I have some bad news; you have cancer and Alzheimer's." The man replies, "Well, at least I don't have cancer."

Knock knock! Who's there? It's Dave! Dave who? Dave proceeds to break down crying at the realization that his grandmother's Alzheimers has progressed to the point where she no longer remembers him.
