Comedy with a victim who hasn't been told it's comedy yet.

means A mischievous trick played on someone for amusement, ideally harmless and eventually forgiven.

from Of murky origin — it surfaces in English in the 1500s meaning a malicious or mischievous trick, related to the now-rare verb 'prank' meaning to dress up or show off ostentatiously. Some link it further back to Low German or Dutch roots meaning to caper or bend, but the trail goes cold fast — etymologists mostly shrug and call it 'origin unknown,' which feels fitting for a word about things sprung on you without warning.
