Corky's Crush - S1.E12

Becca and Corky (in the same class somehow) do a classroom exercise in which paired students must pretend to be married for a week to investigate issues of marriage and family life. Becca is first paired with Lester Fishbein, then switches to Tyler. Neither works out terribly well. Corky, on the other hand, is paired with the new girl (Shannon Dougherty of 90210), upon whom he develops a crush. She only has eyes for the ubiquitous Russo, though, and Corky has to make peace with only being a friend. Meanwhile, Libby's parents hole up at the Thatchers' to continue their love feud. There's a great scene in which Sal Giordano encourages Corky that the right girl is out there.
