Dr. Doofenshmirtz:
In fact, I come from a long line of great meatloaf chefs. The recipe was first created by my great grandmother, Gretel Doofenshmirtz, who passed it down to my grandpa, Jose Doofenshmirtz - weird story there - then he passed it down to my mom, who passed it down to... Roger! Ugh! Naturally, I had to steal it from him, and when I did, I finally found out what the secret ingredient was. The secret ingredient... was hate. Usually it's love, but Great Grandma Gretel had some issues.
