The shirt reads: “DOES EGGNOG EXIST?” The flowchart branches three ways: YES → DRINK IT, NO → MAKE SOME, UNSURE → EGGNOG-STIC.
It is drawn as a proper decision diagram, boxes and arrows, with a mug, a whisk and a question mark illustrating each outcome.
Every path leads somewhere reasonable, which is more than most flowcharts manage. It is the most structured joke in the eggnog series and the one that rewards reading all the way down. For December, and for anyone who likes a pun with a schema.
