227 - Season 2 Episode 7 Come Into My Parlor

When Brenda meets a cute boy she decides to invite him to her party Saturday night. After getting permission to actually have the party, she then hears Sandra tell a story about how when she was young and wanted to get to know a boy better, she would ""mistakenly"" tell him the wrong day of the party. Brenda tries the idea and invites Ken over for Friday night instead, hoping that when he gets there he will meet her parents and stay for dinner. But Mary and Lester decide to go out to eat and are not home when Ken arrives. Brenda decides to let him come in anyway, just to have a drink, but then Calvin shows up to drop off chairs for the party. When she tells them they need to leave, Mary and Lester arrive home and the boys hide. Mary and Lester eventually catch the boys in the house.
