Clean Slate (S04E17)

When Drakken steals the Memory Recovery Machine in order to recall his ingenious plan to take over the world, things don't exactly go as planned and the machine ends up exploding all over Kim. Kim's fine, save for one small problem…she can't remember anything! Can Ron help her re-learn everything...including the all important fact that they're dating, and bring back the old Kim before it's too late? (iTunes)
