Retired clown Galahad has a son. However, upon registering his son in town, he answers the first question "Yes, Sir!" The registrar then writes the baby's name as "Sir Galahad" (a wrench in Mr. Galahad's plans-his son was originally to be named Underdunk). Galahad wishes Sir to be a clown just like him, but Sir would rather be a gallant knight. One night, he has a dream of being a knight and saving a beautiful princess from an evil dragon. However, once that's over, there aren't enough dragons left, and so Sir grows old, his wife grows larger, and his brood of children also grows. With not much to do, Sir spends much of his waning years doing menial household tasks. Near the end of his life, a new threat emerges, and Sir, now an old man, heeds the call. However, he doesn't survive, and is killed. The young Sir wakes from his dream, and decides that he will follow in his father's footsteps.
