OK - Guess we can now consider ourselves officially informed. Would that make us "Informed sources".
From a synopsis of the 1951 movie - Alice in Wonderland:
Throughout the course of the film, the Hatter pulls numerous items out of his hat, such as cake and smaller hats. He and the Hare also break the laws of physics more than once; they pour tea cups and plates out of tea kettles, and the Hatter is seen eating plates and other inedible items at the tea party, also the March Hare asks the Hatter for half a cup of tea, and the Hatter cuts his tea cup in half and pours him the tea. His personality is that of a child: he is angry one second but happy the next. He also takes an immediate liking to Alice after she tells him she's a fan of his singing.
