This slip up takes place in the episode where DJ throws a surprise party for Kimmy and everything goes wrong. It also takes place in the beginning credits. If you watch in the beginning credits, you will see Stephanie with her Scotty Dog shirt on (Scotty Dog on the back). Then in the beginning of the episode... you can see that Stepanie has the same shirt on, but the Scotty Dog is in the front!!! So the slip up is in the beginning credits the whole time!! Definite slip up!
