Continuity mistake: When Porky Pig falls asleep in his boat, he is wearing a red shirt. In his dream, a big fish cuts off the red shirt to cook a now naked Porky.

Plot hole: When Oliver attempts to lift the drain grille in order to get the drunk's car key, he claims it is too heavy. Yet when Stan gets his umbrella stuck down there, Oliver manages to lift the grille without any effort.
Suggested correction: Ollie doesn't say too heavy, he just says "this thing is heavy."
Continuity mistake: When we see the "Lump Massager" at work on the lump on Wile E. Coyote's head, you can see that there are three valves on the machine, but when we see Wile E. at work on his drawing board in the next shot, there are now two valves on it.
