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's Doodle / Doug's Runaway Journal - S1-E10
