Old comment I know, but I had to say it.



If you've ever read Calvin and Hobbes, you'll know that a few of the running gags, such as The Noodle Incident, and Hamster Huey And the Gooey Kablooie are not covered in detail, but are only referred to by those terms.



Bill Watterson has stated that the reason he left the details out is because the reader is sure to come up with something even more outrageous than he ever could.
