The shirt reads: “dyslexic devil worshippers sell their souls to Santa,” with the last word in red and wearing a small Santa hat.
Five lines of white lowercase with the final word blown up, and no illustration beyond the hat.
The two words are anagrams of each other, which is the entire joke and an old one. Setting it in a plain sans-serif rather than anything spooky is the right call.
For Christmas, for anyone who enjoys a joke about letters, and for the office party.
