King's Legs
At the pointed request of Tiffany Aching, the Nac Mac Feegle revisted a scene of havoc which they and Wee Mad Arthur had brought about at the King's Head in Ankh-Morpork.
Using their hitherto unsuspected talent for reassembling and generally making good - they had already surprised Tiffany and a hapless coachman by turning thousands of broken glass shards back into a tasteless mirrored ball to be hung over a dancefloor - the Feegle, assisted by Arthur, rebuilt the pub.
But the only one to notice they'd rebuilt it back-to-front was Daft Wullie. To suit the new ambience, a new pub sign appeared, which nobody will own up to painting, which after some consideration was called The King's Legs.
The King in question, from context in I Shall Wear Midnight, would appear to be Lorenzo the Kind, described as a none-too clean man in a dirty wig with a huge boil on the back of his neck. As the pub sign makes only too apparent.
