Sir Galahad is a supporting character in Monty Python and the Holy Grail.
Sir Galahad is the third knight to join King Arthur and the Knights of the Round Table. On his quest for the Holy Grail, he comes across Castle Anthrax which he mistakes for the hiding place for the Grail because it has a Grail-shaped beacon. Even though he is given hospitality by the castle's women Sir Lancelot and the other knights come to "rescue" him, although Galahad refers to Lancelot as "gay". Later on, Sir Galahad is killed after trying to answer three questions to the Old Man at the bridge.
