List of title screen gags

When The Simpsons opening sequence was reanimated for its conversion to high definition in 2009, initially, during the screen showing the title, only one gag was used: a three-eyed crow would fly by it. Starting with the Season 21 episode "Bart Gets a "Z", the gag would become a changing gag for each episode just like the billboard gags, the chalkboard gags, and the couch gags.
