The Greg Kihn Band would be wrong

A la Cliff Clavin, here are twelve possible Jeopardy categories at which I would clean up...

• DC Comics
• Marvel Comics
• Kevin Smith
• The Periodic Table
• Bob Dylan
• The Internet
• Indiana High School Basketball
• Webcomics
• Food science
• Norse Mythology
• South Park
• 80s Music

I think that's about it, and it avoids a whole lot of areas that Jeopardy often covers - geography, literature, history.
