Maybe Alfred E. Neuman should start worrying. After 67 years, the publishers of Mad have announced they won't be producing any future issues with new content, just rehashing "classic" content. I'll be honest, I wasn't even aware Mad was still being published at all. I haven't read an issue since the 1980s when I became a teenager and the material just didn't seem that funny anymore. Playboy became much more interesting (like most young men, I only read it for the articles).
Still, I remember having some gut-busting laughs reading Mad as a kid so it's kind of hard not to see this as the end of an era. Here's looking at you, Alfred.
