scar
Explanation
This is a single-panel comic built around a wordplay joke involving scarification and tree species.
The header text reads: "Scarification idea: Have it look like some trees were in love and cut their initials in you."
In the image, a man is showing another person a scar on his chest. He says: "And when I awoke... I found THIS." His chest has a heart carved into it with the names "ASH" and "HOLLY" inside -- as though two trees carved their initials into him, the way humans traditionally carve their initials into tree trunks.
The joke is a role reversal: humans commonly carve hearts with their initials into the bark of trees as a romantic gesture (e.g., "J + M" inside a heart). This comic imagines the reverse -- trees that are in love carving THEIR initials into a human. "Ash" and "Holly" are both common tree species (Fraxinus and Ilex, respectively), so the names work both as plausible human names and as tree names, making the gag work on both levels.
The additional humor comes from the man presenting this as though it is a mysterious or alarming event ("And when I awoke..."), as if enchanted trees performed this act on him while he was unconscious -- a fairy-tale scenario played straight. The header text framing it as a "scarification idea" adds another layer, treating what would be a bizarre and disturbing experience as a trendy body modification concept.
