Explanation
The comic shows a single panel of a distressed-looking man in a tank top staring at his own hand, on which he has written "SAY HI TO MOM." The caption below reads: "Note to self: No more notes to self on masturbation hand."
The joke is straightforward bathroom humor. The man wrote a reminder on his hand to call or greet his mother, but then realized -- presumably mid-act -- that having a note about his mom on the hand he uses for masturbation creates an extremely awkward and disturbing juxtaposition. The humor comes from the collision of the mundane (writing reminders on your hand) with the private (masturbation), and the implication that he learned this lesson the hard way.
The votey panel shows a hand with "WHAT I DO:" written on it and the words "GREAT JOB, WINNER!" in a speech bubble, suggesting the man has replaced the mom-related note with a self-congratulatory message for his hand, which is equally absurd but at least avoids the Oedipal discomfort of the original note.
