This is a very rare,and pretty good episode from the latter part of first season.It is rare,because this time it is not Lucy who hatches up a crazy scheme,it's Viv and the chemistry teacher.Are there any other episodes where someone else hatches up one of the crazy schemes that Lucy was known for?

I will not spoil the ending,except to say it is funny,and that Lucy is just as gung ho when she learns what the next subject will be -Viv and the chemistry teacher groan,and say,"Oh,no! Not again!"-as she was when she and Viv sign up for Chemistry class.Any guesses as to what the next class is?
