Which Family Guy episode featured the Bill Cosby beating up a midget gag?

You're likely thinking of the "Road to Europe" episode of Family Guy, which aired in 2009. The episode features a scene where Peter Griffin, dressed as Bill Cosby, gets into a physical altercation with a dwarf in a bar. However, it's important to note that the scene is a parody of Bill Cosby, not a direct endorsement of his actions or a depiction of real-life events.

It's crucial to remember that Family Guy often uses satire and dark humor to criticize and poke fun at various topics, including celebrities. The episode's writers likely intended this scene as a satirical commentary on Cosby's persona and the perception of his character, not an accurate representation of his personal behavior.
