JESS: Just lay low, it’ll come.
LUKE: Does it act all peaceful and Bambi-like and then suddenly attack like the rabbit in Monty Python?
Bambi, previously discussed.
Luke refers to the Killer Rabbit of Caerbannog, a character in the film, Monty Python and the Holy Grail, previously discussed. In the film, the Knights of the Round Table are told a particular cave is guarded by a fearsome monster – to their initial relief, this beast turns out to be what appears to be an ordinary white rabbit. No longer taking the warnings seriously, they approach the rabbit confidently – only for one of the knights to be instantly decapitated by a flying bunny. The rabbit kills two more knights and seriously injures several more before it is defeated.
