Well, now, uh, Launcelot, Galahad, and I, wait until nightfall, and then leap out of the rabbit, taking the French by surprise – not only by surprise, but totally unarmed!

Our reading
An editorial interpretation.
Bedevere describes an elaborate plan to surprise the French by leaping out of a rabbit. The wording then tangles surprise with being unarmed, as if that were an extra advantage. The confident planning and awkward boast give the speech its absurd humor.
