The "Cry.sig on Infinite Net.Earths" was a parody of the DC Comics story Crisis on Infinite Earths. Like that story, it allowed LNH writers to change things about their characters. For example, before "Cry.sig", Cheesecake-Eater Lad was married and farted a lot. After "Cry.sig", he was single and made cheesecakes. It was like the earlier Cheesecake-Eater Lad never existed. In American comic books, this is called a retcon.
