Ain't She Tweet (1952)

Continuity mistake: When Sylvester is looking at Tweety Pie in the pet shop window, you can see the cage next to Tweety's cage is much further away, but a couple of seconds later it is now next to Tweety.

Trivia: When Sylvester picks up a brick and says "Laugh this off!", there is a building beside him which says "I. Wyner Co." - a reference to the Warner Brothers background artist Irv Wyner.
