S06E18 - Courrier du cœur
Synopsis
Richie temporarily takes over a local newspaper's advice column but only tells Fonzie about it. Potsie and Ralph, in an attempt to solve their continuous bickering problem, write in to Richie's column. Richie, via the column, suggests they literally draw a line down the center of the room and for Ralph to stay on one side and Potsie on the other.
