The Winslow's foster child, 3J, yearns to know his biological parents. 3J's mother is an unmarried waitress recovering from drug addiction, but she doesn't want 3J to reunite with her yet. Rather than upset 3J, Carl promises to search for his mother when 3J is older. After bringing the unknowing 3J to the diner where his mother works so she can see him, Carl informs the elated boy that the Winslows will adopt him.
Meanwhile, Myrtle Urkel returns to town after learning how much Eddie loves Greta, and Laura suggests that the feuding girls compete in a boxing match to determine who should date Eddie.
