Tea Cosy (American English; tea cozy) - a cover for a teapot, traditionally made of cloth or wool, used to keep the tea warm while it brews. Tea cosies may be embroidered; perhaps to complement a fine set of china. The traditional British handknitted cosy tends to resemble a woollen hat, often featuring a bobble on top. According to comedian Billy Connolly, if a man is left alone in a room with a tea cosy, and he does not attempt to wear it, he is not be trusted.

Some tea cosies are just evil.

The Terrorist Tea Pot is a set including the tea pot and the balaclava tea cosy.

There you are minding your own business, getting through the day as a humble bank teller when the mundanity of your everyday working life is shattered by the rather rude intrusion of some terrorists hell-bent on death, destruction and a few million pounds in cash. What else is there to do in such testing circumstances, before submitting to being bound, gagged, shackled, tortured and killed, than make a nice cup of tea? And there's no better teapot in which to make one's final cuppa than this, the work of a truly fevered creative imagination... the one (and only) Terrorist Teapot. Looking for all the world like a balaclavad-up hood, complete with tight-fitting mask and fiendish squinting eyes, it makes a mean brew, whether in the teeming backstreets of Peshawar or simply in one's flat in Pimlico. Enabling you to surf the very crest of current modishness and claim to be ahead of the zeitgeist, the Terrorist Teapot is the gadget over which to infuse, confuse and possibly diffuse. To hatch plots and plans, buy a few tonnes of fertiliser, and get spectacularly arrested. You have been warned.
