Alice, the March Hare, the Hatter, and the Dormouse at the tea party.
The Mad Tea Party, sometimes referred to as The March Hare's Tea Party, (incorrectly) The Mad Hatter's Tea Party, or simply just The Tea Party, is the most famous scene in Lewis Carroll's Alice's Adventures in Wonderland that appears in the seventh chapter "A Mad Tea-Party". It ha been featured in every single adaption of Alice in Wonderland.
Alice, after talking to the Cheshire Cat, decides to go to the tea party. There she meets the March Hare, the Hatter, and the Dormouse. The trio speak in riddles and nonsense. After a while, Alice leaves, stating that it is "the most stupidest tea she has ever been to in her life".
Do to the Hatters popularity, most people mistake it as his tea party, although the book clearly state that it takes place at the March Hare's house.
