Doofenshmirtz to the Diagnosis

When I visited Oogie Boogie Bash last year, the scariest looking villain to me wasn't the intimidating Hades or the sinister Judge Doom or the bratty Sid. It was actually Dr. Doofenshmirtz, from Phineas and Ferb.  In cartoon form, he's kind of goofy looking and innocuous.  But in person from, his long face and odd hair and sunken eyes make him look a little ghastly.  He looks the part, but this is why sometimes, cartoons should stay cartoons!
