Did the round table have enough seats for all the knights?

At first, they did not. After many rounds of musical chairs, they decided that something needed to be done about the unusual symmetry of the table. Eventually, they called in the royal jiggler (the table maker) who immediately ha a solution to the problem: a death match to decide who would stay alive and conquer a seat! After much bloodshed, only a few knights remained. They made a quick truce and pinky promised not to kill each other. Then, they all celebrated by calling in the royal concubines and having a quite satisfactory gangbang while drinking the finest Scotch wine in all the land.

So in the end, yes, they did have enough seats.
