Boffo Novelty and Joke Shop

Located at No. 4, Tenth Egg Street, Ankh-Morpork. The spiritual home for all those who consider that fart powder is the last word in humour (which in many respects it is). The proprietor is Jack Proust, who also runs a thriving mail-order business to more seriously-minded customers in outlying reaches of the Disc, and who has therefore got a lot to thank Moist von Lipwig for. This was also the very first business in Ankh-Morpork to accept one of the new-fangled paper dollars, which promptly circulated next door to the newsagent/tobacconist, who in turn kept the money in circulation to the butcher's shop across the road.

One of Boffo's far-flung customers was Eumenides Treason, a Witch who bought many of her decorations in order to gain respect (through instilling fear) from the locals. This was discovered by her final apprentice, Tiffany Aching, who decided to name this "putting on a show" type of deception "Boffo".

in I Shall Wear Midnight, we discover the shop is not a one-man-band but a family firm. Jack would appear to have a brother, Derek, who is a mousy, perpetually worried little man with no perceptible sense of humour. Their mother is the driving-force of the shop, creating all the successful gags in her downstairs laboratory workroom which has more than a hint of Igor to it.

We discover Mrs Proust is, to all practical intents and purposes, a City Witch. She is certainly held in mutual esteem by Granny Weatherwax, despite the fact the two only meet for the first time at Tiffany Aching's introduction.
