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, but a moment later Doug's reflection is properly backwards as it should be.

Other mistake: A time card reads 6,000,002 BC, when it should've read "60,000,002 BC". (00:07:12)
Continuity mistake: When Marshall first finds Trip's letter, he holds it from the left side. In the close-up, he's holding it from the right side. (00:02:10)
