S1·E15 Brenda's Last Date

Pearl asks Mary if Lester would have a man-to-man talk with Calvin about sex and Brenda asks her parents if she could go to the dance Friday night. They believe that she is too young to date (14). From Mary's persuading, Lester talks to Calvin and ends his talk with, ""If you mess around with my daughter, I'll rip your head off."" Scared, Calvin breaks the date anyway. But Brenda still wants to go and comes up with a plan. Brenda tells her parents that she will go to the library Friday night, while Calvin tells his grandmom that he is going to see Haley's Comet. When Mary finds out, she goes to the dance and takes Brenda home. At home she and Brenda have a heart-to-heart talk, where Mary says she and Lester will relax the rules a little.
