Look Hard: In the episode "Picture This", Dog was taking a picture of a shoe, twig, and bone together in the beginning. When Lola flew in, she was wearing a red dress except it had white polka dots. When she was talking to CatDog until she left, she was waring the regular dress. Then when Lola flew out of CatDog's house, she was wearing the polka dot dress once again.
Lube: That was the most beautiful thing I've seen since cheesy-crust pizza.
Lola: (reacting to Dog's pictures) I never kissed a moose in my life! Okay once, but it was in a school play.
Shriek: You should see me in my footsie pajamas!
Lube: Duh. You should see me in her footsie pajamas!
