Opie complains to Andy about how his new history teacher Ms. Crump is a mean old woman who likes to assign extra homework. Andy tells Opie it's not important if he doesn't know every answer, which leaves Opie believing history isn't important. Now Andy has to show Opie, and his class, how much history matters before Ms. Crump decides to quit.

Opie develops a case of puppy love for a girl in his class, but is crushed to find she isn't interested. Barney tries to lift his spirits by letting Opie hang out with him and Thelma Lou awhile. It works great, until Opie forgets his crush and sets his sights on Thelma Lou.
