If someone says you are mad as a hatter, they are accusing you of being quite irrational. The sense of madness here is "suffering from a disorder of the mind; insane." This phrase usually refers not to someone who is actually insane, but rather to a more normal person who is behaving in an irrational way.
The phrase emerged in England in the 19th century. Hatmakers in those days used a lot of felt that was treated with chemicals including lead, arsenic, and mercury.
Unfortunately, those chemicals are highly toxic. The symptoms of such poisoning include palsy, confused speech, and distorted thinking. Today, making hats is a much safer profession, but the phrase survives.
An interesting alternate explanation of the phrase derives hatter from Anglo-Saxon atter (poison), which is related to adder (a poisonous snake whose bite was thought to cause insanity).

An outstanding tv show on AMC where people smoke, drink, and pretty much cheat on the regular. It was created by Matthew Weiner. It's currently airing its second season, as the first season was a booming success as it received best television drama by the Golden Globe's. Jon Hamm (Don Draper) also won best actor from the GG's. This show depicts the life of men and women in the early 60's, and the show is based on groups that work for "Sterling Cooper", an advertisement agency. It shows the flaws in people and what they'll do to cover them up.

Cesar: Where can I go to get a spine massage?
Randy: I was just at your house man, all we needed to do
was change into robes and I would have oiled that spine up. I give mad endings though.
