Blood is thick rule

Image transcription: a four panel comic. First panel is of a dark haired twink sitting on a chair while a dark haired doctor wearing a white lab coat and holding a syringe, standing to the right of the twink, says “it’s time to run a blood test”. Second panel shows the doctor expelling blood from the syringe into a Petri dish. Third panel shows red blood cells sitting a class room at small wooden desks which have white pieces of paper on them. The fourth panel is a close up of one of the red blood cells saying “oh shit”.

The comic has a comment from a user named “Dante’s-infernal-chili, saying “This is the funniest shit I’ve seen all goddamn week”
