"On second thought, let's not go to Camelot. It is a silly place."
Camelot was the location of King Arthur's court.
Prior to his search for the Holy Grail, Arthur gathered knights to join the round table at Camelot. Upon the group reaching Camelot (which Patsy pointed out was only a model), the Knights of the Round Table performed a song-and-dance, prompting Arthur to reconsider going to Camelot, because it seemed too silly a place.
