Doug Gets His Ears Lowered / Doug On The Wild Side - S1-E8
Other mistake: Doug Gets His Ears Lowered: Doug tells Porkchop about his old barber, Big Al. In the flashback, Big Al wears a smock with his name patch and a pocket containing scissors, but the problem is Al's reflection is not reversed in the mirror. (00:01:50)
Other mistake: At Honker Burger, when Skeeter introduces Doug to Patti, the lower half of Doug's body and both of his arms are missing; the animation is incomplete. (00:20:55)
Doug is Quailman / Doug Out in Left Field - S1-E12
Other mistake: Doug Out In Left Field: When the kids are carrying Patti at the end, there is a boy behind Doug whose blue shorts keep flashing green, and his light green hair keeps flashing dark green. In the next shot, his hair stays dark green. (00:22:21)
Doug Can't Dig It / Doug Didn't Do It - S1-E5
Other mistake: Doug Can't Dig It: After Judy finishes her performance in Doug's imagination, when the curtains close behind her, she is layered behind them for a split-second. (00:03:19)
Doug Can't Dig It / Doug Didn't Do It - S1-E5
Other mistake: Doug Can't Dig It: When Doug imagines Judy performing at the school, as Judy says, "My soul throbs," her right sleeve turns purple twice. (00:02:52)
Doug Takes a Hike / Doug Rocks - S1-E4
Other mistake: Doug Rocks: When Doug and Skeeter win the contest to see The Beets, when Roger says, "Gee Funnie, I guess even a loser like you gets lucky once in a while," the logo on Roger's shirt is reversed. (00:17:23)
