The knights of the drop-leaf table

The six knights clanking round the castle corridors are driving King Artie up the wall. He can't even visit the privy without them pestering him about jousting tournaments, the Code of Chivalry, the proper way to polish armour, and if Sir Tralahad sings another of his ridiculous songs Artie will chuck him off the ramparts. What the knights need, Queen Gwinnie says, is a room of their own for meetings. But that's easier said than done. And trouble really starts when someone brings a feast to a table that's more drop-leaf than round.
