Humble Pie - S6-E8
Continuity mistake: At the end of the episode when Morgan tells Sabrina she will be working in the coffee house with her, she put on the apron and its the right way, then it flashes back to when she says "we're gonna have so much fun together" and the apron is on backwards with the label sticking out.
Answer: In the S6 E18, "I, Busybody" Salem got permission from the Witch's Council to be human for one day to meet his pen pal, Roxie. It was all a point of view camera shot.
