Doug En Vogue / Doug's Mail Order Mania - S4-E4
Continuity mistake: Doug En Vogue: While Doug is at the store, he tries to attain a new original look for himself. When he's looking at his reflection dressed as a rapper, the necklace with the word "RAP" is not a reversed image in the mirror, but a moment later Doug's reflection is properly backwards as it should be.
