When Launchpad is in the Darkwing suit at the beginning, he is pantsless like the real Darkwing. After he crashes into the closet door and falls to the floor, he is seen wearing his usual trousers and boots, before being pantsless once again when he gets up.
As Drake watches the news story "exposing" Darkwing Duck's identity, his sleeves are down to his wrists. After cutting to the television and then back to Drake, his sleeves are suddenly rolled up before going back down again 10 seconds later.
