Much like Hobbes' reality, it is assumable that Bill Watterson wants the reader to make up his or her own perspective of what ridiculous thing could have happened because of Calvin. Throughout the comic, the most that we learn is that it was presumably done by Calvin (though he maintains that he had been framed) and has caused him to worry about possibly not getting any presents from Santa Claus.

It appears to have happened at school due to Calvin yelling out loud, "She told you about the noodles, didn't she?!" when his mom came home from a parent conference. When Hobbes commented on the Incident, Calvin claimed that it was rather an accident
