Pacman takes a bite out of the head
When shaving a design into the head, it is not a good idea, generally, to continue when the arm and hands are dying from exhaustion.
From the recent attack of falling blocks in Tetris, the first other game to mind was invariably that of Pacman. That and the fact that the designs of the ghost and Pacman were relatively easy to shave into hair. Especially using the aid only of mirrors.
Carving a pair of cherries into the very back of the head proved not as fruitful as first thought. A gash and blood spat the evidence of taking to task without a quick rip.
