When drawing, sketchy lines (often done with a blue pencil, since that colour won’t photocopt) are called ‘roughs’; the final inked version, in black, is called the “clean” version. In this strip, the roughed-in character (nicknamed ‘Rough’) has changed his dirty shirt for a ‘clean’ one. It’s a visual pun based on animation terms.
I don’t geddit!!
