I love how Candace ended up building something instead of the boys, and as usual it getting taken away 'cause of Doof. And now...my favorite part...Doofenshmirtz's plan was epic. Definitely one of my favorites of all time. How he got zapped and nothing happened was downright hilarious.
Although, in the end, he got zapped when it was the beauty mode thing, right? So I wonder what he looked like then....
