"Actually, almost anything you see with Calvin and Hobbes on it is copyright infringement. Here is the complete list of things Bill Watterson has approved for mass production:

• Books
• Two calendars (1988-1989 and 1989-1990)
• A textbook called Teaching with Calvin and Hobbes
• One t-shirt for a traveling art exhibit"
