Mad as a Hatter is the debut EP by Australian hip hop group Def Wish Cast. It was released in 1992 on vinyl by Random Records. All production and turntablism is by DJ Vame, except "Proppa Ragga", which was produced by DJ Sing. "Proppa Ragga" was the first Australian hip hop track to receive international recognition, albeit at Norway, coming in at number 2 on its NRK's Hip Hop show (hosted by Tommy Tee). In 2007, a copy of Mad as a Hatter sold on eBay to a German bidder for more than A$430. The EP samples Walt Disney's Alice in Wonderland in the title track.

Usage examples of "mad as a hatter".
When she was growing up and displaying every indication of being as mad as a hatter-hearing voices where none existed, that sort of thing, answering questions before any were asked-and alternating fits of high mania and low depression-well, the Millers had always managed to forgive and forget or, at least, to ignore.
