Explanation
The Joke
An elderly couple sits together reflecting on the progression of their forgetfulness over the years. At first, the man would forget little things like where his keys were. Then he would forget names, faces, and why he came into a room. Eventually he would forget entire people, becoming unfamiliar with relatives. The couple realizes that they had to go out together specifically to talk, because they had realized they were forgetting each other too.
The final panel reveals a darkly poignant twist: the man says he is "moving forward" and has "mostly forgotten" his wife. Sitting alone under a tree, a passerby asks whether the tree he is talking to is "the dancer or the tree," and the man replies, "They are equivalent." He has deteriorated to the point where he can no longer distinguish between a person and an object, suggesting he is now deeply lost in dementia.
The Humor
The comic uses the structure of a familiar, relatable complaint -- forgetting where you put your keys -- and gradually escalates it into something genuinely heartbreaking. The humor is dry and bittersweet rather than laugh-out-loud funny. The final image of an old man talking to a tree, believing it to be his wife (or unable to tell the difference), lands as both absurd and deeply sad. SMBC often walks this line between comedy and existential tragedy, using the comic strip format to deliver an emotional gut-punch disguised as a joke about aging.
