It would be good, of course, if we could say " Calvin is back". It's not true, Bill retired, but on March 10, Calvin & Hobbes appeared in a strip, "The Adventures of Aaron". Some fans find it good, to keep Calvin´s memory alive.

I, personally, think it's an outrage, who did this should be ashamed of himself. It's incredible to think that somebody uses Calvin's popularity to sell his work. Calvin will be back only when Watterson decides so, not when some Aaron Warner wants. He even has the guts to write things like : "This is just a normal stuffed Tiger with suction cups on its feet. That is not Hobbes." or "Any similarities between Ghost of Calvin and Calvin & Hobbes is purely coincidental."

Ridiculous. See it for yourself...
