Why does the mad hatter in Alice in Wonderland 2010 say fez after he goes mad?

In Tim Burton's "Alice in Wonderland," the Mad Hatter, portrayed by Johnny Depp, mentions "fez" as part of his whimsical and nonsensical dialogue that reflects his madness. The fez, a traditional brimless hat, symbolizes his quirky personality and is a nod to the absurdity that permeates the story. This line also underscores the Hatter's character—bizarre yet endearing—capturing the essence of the surreal world Alice finds herself in. Ultimately, it's a playful expression of his fragmented thoughts and the chaotic environment of Wonderland.
