German Squirmin' / The Means Justify the Trend

S1 E9: German Suirmin': Todd is not exactly acing his German class, so he replaces his teacher with a guy who speaks only German - so when Dick and K come in for a parent-teacher conference they can't understand what he's saying. Sounds like a plan until Todd is in a bind where he actually needs to know German. The Means Justify the Trend: All of a sudden every girl in school is blindly following the latest trend set by celebrity Heather Hartley. Riley is appalled at what clones everyone has become, so she replaces Heather with the most average girl around - which turns out to be herself. But now everyone is acting like Riley, which doesn't exactly solve the problem.
